[2026-07-10 09:14:22] Customer: Hi, I’m running a self-hosted photo library on my home server, and the mobile app stopped backing up photos overnight.
[2026-07-10 09:14:48] Support: I can help with that. Are you able to open the web interface from the same network?
[2026-07-10 09:15:07] Customer: Yes, the web app loads locally at 192.168.1.40:2283. From outside my network it times out.
[2026-07-10 09:15:36] Support: That points to the remote access path rather than the library itself. Are you using a reverse proxy or port forwarding?
[2026-07-10 09:16:02] Customer: Nginx Proxy Manager with a subdomain, photos.mydomain.net. It worked until yesterday.
[2026-07-10 09:16:41] Support: Please check whether the SSL certificate is still valid and whether the proxy host is forwarding to port 2283.
[2026-07-10 09:18:19] Customer: The cert looks valid, but the proxy host was pointing to 192.168.1.35. I moved the container to a new machine last week.
[2026-07-10 09:18:50] Support: That would explain it. Update the proxy target to 192.168.1.40, save, and then test the subdomain in a private browser window.
[2026-07-10 09:20:11] Customer: The web app loads externally now. The mobile app still says “server unavailable.”
[2026-07-10 09:20:42] Support: In the mobile app, open Settings and confirm the server URL is exactly https://photos.mydomain.net, without the local IP address.
[2026-07-10 09:21:30] Customer: It was still set to the local IP. I changed it and signed back in.
[2026-07-10 09:22:04] Support: Good. Does the backup queue start processing?
[2026-07-10 09:22:39] Customer: Yes, it says 143 items remaining. Upload speed looks normal.
[2026-07-10 09:23:08] Support: Great. One more recommendation: reserve 192.168.1.40 for that server in your router’s DHCP settings so the proxy target does not break again.
[2026-07-10 09:23:44] Customer: Makes sense. I’ll add a DHCP reservation now.
[2026-07-10 09:24:16] Support: After that, restart only the proxy container if needed. The photo library container can stay running.
[2026-07-10 09:25:02] Customer: Done. Uploads are still running and new photos are appearing in the timeline.
[2026-07-10 09:25:31] Support: Then you should be set. The issue was the reverse proxy still pointing to the old server IP, plus the mobile app using the local address.
[2026-07-10 09:25:58] Customer: Thanks, that fixed it.
