[09:14] Customer: Hi, after updating my self-hosted photo library last night, the mobile app stopped backing up new photos. Existing photos are still visible.

[09:15] Support: Hi! I can help with that. Which server and mobile app versions are you running?

[09:16] Customer: Server is 1.112.1 in Docker, and the Android app is 1.112.0.

[09:17] Support: Thanks. When you open the backup screen in the app, do you see an error or pending uploads?

[09:18] Customer: It shows 47 pending. If I tap “Start Backup,” it briefly says “Connecting” and then stops.

[09:19] Support: That usually means the app can reach the server but cannot start an authenticated upload. Are you connecting through a reverse proxy?

[09:20] Customer: Yes, Nginx Proxy Manager. The server is at photos.example.net.

[09:21] Support: Could you check whether the server URL saved in the app begins with https:// and does not include an extra path or trailing space?

[09:22] Customer: It’s set to https://photos.example.net/api. I think an older setup guide told me to add /api.

[09:23] Support: Please change it to https://photos.example.net, sign in again if prompted, and retry one photo.

[09:25] Customer: Done. One photo uploaded, but a video failed with “413 Request Entity Too Large.”

[09:26] Support: Good, that confirms the original connection issue is fixed. The 413 response comes from the reverse proxy’s upload-size limit. In Nginx Proxy Manager, add this under the proxy host’s Advanced configuration:

client_max_body_size 0;

[09:27] Customer: Does 0 mean uploads are disabled?

[09:27] Support: In this directive, 0 disables the size limit. If you prefer a fixed limit, you could use something like 10G instead.

[09:29] Customer: I added it and restarted the proxy host. The video is uploading now.

[09:30] Support: Great. I’d also recommend enabling background activity and unrestricted battery usage for the mobile app so Android does not pause larger backups.

[09:31] Customer: That was set to “Optimized.” I changed it to “Unrestricted.”

[09:32] Support: Perfect. Leave the app open until the current queue starts moving consistently. After that, background backup should continue when the phone is charging or on Wi-Fi, depending on your backup settings.

[09:34] Customer: The queue is down to 39 and both photos and videos are uploading. Looks fixed.

[09:35] Support: Excellent. The two issues were the obsolete /api suffix in the mobile server URL and the reverse proxy’s request-size limit.

[09:36] Customer: Thanks! Will I need to change anything on my spouse’s phone too?

[09:36] Support: Yes. If that phone also uses a URL ending in /api, update it to https://photos.example.net. The proxy-size change applies to everyone, so no additional change is needed for video uploads.

[09:37] Customer: Got it. Thanks for the quick help.

[09:37] Support: You’re welcome! Have a great day.
