    I have a fresh dedicated server ready and want it transformed into a fully-functional hosting and email platform, all managed through cPanel. Here’s the scope: the server needs a clean OS install (your recommendation is welcome), hardening, cPanel/WHM configuration, DNS setup, and the creation of a reliable mail server with SPF, DKIM, DMARC, and secure SSL for both web and email traffic. I’ll supply the domain details and any licence keys you request; you handle the rest—from initial partitioning to final deliverables that let me log in, add a new website, and send a test email without landing in spam. Acceptance criteria • SSH access secured and root login restricted • cPanel/WHM running smoothly with named services (Apache, MySQL/MariaDB, Exim, etc.) o...

    My Azure Container App is already live on its default *. address; now I want it to answer to my existing domain that sits with Squarespace. I have full access to both the Azure subscription and the Squarespace DNS panel, so the piece that’s missing is the correct wiring and SSL. What I need from you is straightforward: add the custom domain to the container app in the Azure portal / az CLI, create or bind a certificate (Azure-managed is fine, but if you prefer Let’s Encrypt that works too), then walk me through—or directly apply—the required A or CNAME entries in Squarespace so the site serves over HTTPS without any security warnings. The job is complete when the domain resolves everywhere, the SSL padlock is green, and I have a short note of the steps and record ...

    My personal Gmail has been compromised and all standard recovery steps I know—namely the recovery-email and phone prompts—have failed. Google’s automated flow keeps looping me back to “unable to verify,” so I’m locked out even though I can still see activity alerts landing on my phone. I’m looking for someone who knows Google’s account-recovery system inside out, can guide me through the right sequences (or submit the correct escalation forms), and help me regain full access without violating Google’s Terms of Service. Ideally you have a track record of restoring accounts after similar unauthorized takeovers and can show me how to harden security once we’re back in.

    has suddenly dropped offline. I first suspected the domain setup, corrected that, yet every browser still throws DNS_PROBE_FINISHED_NXDOMAIN. No recent changes were made on my side, and although support tickets are open with the host, they have not resolved the issue. My husband holds the log-ins for both the registrar and hosting control panels, so you will have full access once we kick off. At the same time, our second site——works on desktop, but the “Book Online” button has vanished on mobile. The styling and functionality were fine before, so I need that call-to-action back in place without disturbing the rest of the layout. What I need from you • Bring back online and confirm it resolves everywhere. • Restore the missing mobile “Book Now...

    I need a technician for future issues like this: I run a mixed Windows 10, Windows 11, and Windows Server environment and critical domain issues are disrupting daily work. Top priority is restoring domain stability—users can’t authenticate, some PCs lose contact with the domain controllers, and several Group Policies refuse to apply. Once the domain is healthy, I also need help with a stubborn boot-loop on one workstation, fine-tuning Windows Defender Firewall rules, and checking a handful of other advanced Windows quirks that have crept in. You’ll have full remote access (VPN + RDP) and I’ll be available for live testing or quick reboots. Typical tools in play here are Active Directory DS, DNS, GPMC, Event Viewer, PowerShell, and Sysinternals; feel free to brin...

    I am ready to retire our on-prem Exchange 2013 server and move everything into Microsoft 365 using a straight cutover migration. The environment is simple: fewer than 50 mailboxes, each well under 50 GB, and there are no public folders to worry about. Your task is to plan and execute the end-to-end migration so that users experience minimal disruption and all data lands safely in the cloud. Key pieces you’ll handle include preparing the source server, running the cutover batch through Exchange Admin Center or PowerShell, managing DNS switchover, and making sure Outlook profiles autoconnect once the mailboxes finish syncing. I’ll provide the required admin credentials and can schedule a maintenance window for any after-hours tasks such as the final MX cutover. A smooth transit...

    Both of my websites sit on a Server4You VPS and I manage them through cPanel. Sometime within the past week the entire sites—not just individual pages—began crawling, and I can confirm that no code or server-side changes were made on my end before the slowdown appeared. I need someone who can jump in today, trace the bottleneck quickly, and restore normal load times. You’ll have full cPanel access to review Apache or LiteSpeed settings, PHP-FPM, MySQL, DNS, SSL, or anything else that could be stressing the box. If you uncover resource spikes, mis-configured caching, or network-level issues at the host, please tune or patch them on the spot and let me know what you did so I can keep things running smoothly going forward. Ideal outcome: pages load at the speed they did...

    My site and its web-mail went dark right after I tweaked a few DNS records, so I need a fresh set of expert eyes to straighten things out. Both the website and our email flow are currently affected. I did recently update the zone—just record edits, no provider switch—so the problem is almost certainly sitting in the A, MX, or related TXT entries. Here’s what I need from you: • Audit the current zone file, spot any mis-pointed A, MX, CNAME, TXT or SPF/DMARC inconsistencies, and explain the root cause. • Correct the records (or provide exact values for me to apply) and verify the site resolves and messages send/receive without bouncing. • Give me a brief hand-over note so I understand what changed and how to avoid a repeat.

    Fix LibreTime Live Stream
    22 hours left
    Verified

    I recently upgraded my station from LibreTime 4.4.4 to 4.5.0 and ever since the change the live input only plays for a second or two before dropping. The Live Master toggle lights up, my encoding software connects, yet nothing is delivered through the public stream URL. Most of my streams run through Icecast, although I occasionally keep a secondary mount active, so any solution has to work cleanly with Icecast at minimum and not break compatibility with other mounts. I’m unsure whether the fault sits with DNS, port forwarding, or LibreTime’s internal live-routing, so I need a full check of: • Input path from encoder to LibreTime • Internal routing within LibreTime (liquidsoap, live priority, etc.) • Output chain from LibreTime to Icecast, including mount-p...

    Our current site does its job on the front end, but the experience behind the scenes is a daily struggle. The admin user interface is clunky, updates take far too long, and on top of that Gmail keeps flagging our outgoing messages because DKIM isn’t aligned. Here’s what I need accomplished: • Email authentication: Pinpoint the source of the DKIM failure, correct the DNS records, and confirm that Gmail reports a solid “PASS” once the fix is live. • Site rebuild: If a move to WordPress is the cleanest path to a friendlier backend, rebuild or migrate the existing pages there without losing content or search equity. I’m flexible on theme choice as long as the editor is intuitive and page speed stays healthy. • Payments: Add Square as our...

    I need an experienced CallHippo troubleshooter to jump in right away and get my account fully operational. The immediate roadblock is a domain verification problem—CallHippo keeps rejecting my domain even after I follow their on-screen steps. I do have full access to my DNS panel, so you can add, edit, or remove TXT, CNAME, or SPF records as needed. Once the domain is green-lit, I also want the platform taken from “brand-new” to “ready for outbound cold calling.” That means numbers purchased or ported, dial-plans created, caller ID set, and any essential integrations (Zapier, HubSpot) switched on. Deliverables (all must be met to mark the job complete): • Domain successfully verified in CallHippo dashboard • All mandatory DNS records (TXT, SPF, D...
