I recently installed syncthing on Debian on a free tier google cloud vm. I installed syncthing v1.2.2 via packages, set-up a syncthing user and group and it runs via systemd the GUI is proxied via nginx. It was working flawless; I added devices and folders without problems.
I recently upgraded to v1.3.0 via packages. I added the device ID of this server on a new syncthing server and when I try to accept the invitation the GUI responds with:
“Connection Error. Syncthing seems to be experiencing a problem processing your request. Please refresh the page or restart Syncthing if the problem persists.”
I discovered I get the same response when I try to adjust anything in the settings, such as set the GUI theme to dark, or add a folder. Apart from this syncthing is syncing current folders with current devices without problems.
I tried:
Because systemctl status gave a warning “The unit file, source configuration file or drop-ins of syncthing@syncthing.service changed on disk.” (I think due to the pkd upgrade): sudo systemctl daemon-reload
restart syncthing
restart vm
I am new to working with linux and commandline. After installing syncthing a few times on different free cloud providers I am becoming more comfortable using the commandline and I think I made a proper installation on this vm.
Thanks for taking the time to read through and I hope someone is willing to help me out a bit.
Actually having checked, I can’t see under what circumstances the race condition would exist, but regardless, the truth lies in your javascript console.
So both when accessing the GUI as well as when trying to do something that changes its configuration, an error emerges from angular.js 9912: xhr.send(post || null); in the function: function createHttpBackend($browser, createXhr, $browserDefer, callbacks, rawDocument)
I copied the whole content of the 413 error:
angular.js:9912
POST domain/rest/system/config 413 (Request Entity Too Large)

EDIT:
I will play with my nginx settings first then Nummer378
EDIT2:
Thanks for the quick response here! It was indeed one of my nginx settings, from a website about hardening nginx I had added the following:
client_body_buffer_size 1k;
client_header_buffer_size 1k;
client_max_body_size 1k;
large_client_header_buffers 2 1k;
After removing this the GUI is working fine again. I do still get the 500 error of the rest/system/upgrade, but I can add and remove devices again.
Thank you very much!!!
