Automatic local URL switching frequently fails

[ShawnTheBeachy]

The bug

I have automatic URL switching set up when I am on my home network. I have the following setup:

External network: Only one entry: my externally accessible URL.
Local network: My Wi-Fi name and local URL

I'm not able to reproduce it reliably, but probably 8 times out of 10 when I open the iOS app not on my local network, it still tries to use the local URL. Restarting the app usually switches it to the remote URL.

Reproduction steps

1. Open the app off my local network.
2. Notice that Immich can't connect to the server. Check the URL, see that it is trying to use the local URL.
3. Reopen the app. Check the URL, see that it is (usually) fixed. Repeat step 3 if not.

Relevant log output

No response

Additional information

Immich's "Location" permissions are set to Always.

when I open the iOS app not on my local network

Do you know if this is happening when you are on mobile data or on a different WIFI network?

[ShawnTheBeachy]

@alextran1502 It happens both ways. The other day I had it happen on mobile data, and today I had it happen while on my work Wi-Fi. Wish I could give more info, but I can't seem to reproduce it reliably...

[alextran1502]

Thanks, I will investigate this

[ShawnTheBeachy]

@alextran1502 Not sure if this is helpful, but I just noticed it actually goes the other way, too. I just opened Immich on my local network, and it continued using the remote URL until an app restart.

[alextran1502]

@ShawnTheBeachy can you let me know where do you confirm the connection info?

[ShawnTheBeachy]

@alextran1502 I'm tapping on my profile photo in the top right corner and checking the "Server URL" in the popup.

[alextran1502]

Ah that is not necessarily reflecting the correct info. There is a caching bug of showing the value. However, it is using the correct url

[ShawnTheBeachy]

@alextran1502 Ah I see! Perhaps there’s overlap with some other bug, then? I just encountered this issue again and I did some testing; the app was non-functional until I did a restart and it showed the correct (remote) URL. Any attempts to refresh the library, view albums, search, etc. just showed a spinner indefinitely. I also checked the logs, and it did say “Resuming session at [my local URL]” even though I wasn’t on my Wi-Fi.

EDIT: Looking at the logs more, it does actually look like the sync was succeeding, though. Perhaps some parts of the UI just aren’t using the correct URL or something…?
