JMP trying to acess server at localhost instead of actual domain

[SvbZ3r0]

I have Jellyfin server behind an nginx reverse proxy at https://customdomain.com/base_url. I have been using this setup since Jellyfin's inception and haven't had any issues. I also haven't changed my configurations recently. Since updating to 1.10.1 (I'm not sure if the issue existed in 1.10.0 since I only had that installed for a single day), whenever I open the client, it takes me to the select server screen instead of auto logging in. When I try to login from there, it tells me "We're unable to connect to the selected server right now. Please ensure it is running and try again.". I'm sure this isn't a server issue since my server doesn't have any access logs relevant to this. From the logs, it looks like the media player is trying to reach https://127.0.0.1/base_url instead of https://customdomain.com/base_url. Relevant part of logs is below:

The server credentials has a LocalAddress key that is being used:

If I delete the server and add it again, I can log in without issues until some (I'm not sure how much exactly) time, when the issue repeats itself. Successful login after deleting and adding the server:
