hi ive been running self hosted bitwarden rs for several years without issue on my server, yesterday it began to throw a bad gateway error. i didnt change anything in the server or config so unclear why this is happening, and now cant access at all. i tried both restarting the container and server and updating but no difference.
these are 3 of the most common messages showing in the error log:
30579#30579: *4456 upstream prematurely closed connection while reading response header from upstream, client:
3737#3737: *8366 recv() failed (104: Connection reset by peer) while reading response header from upstream, client:
21458#21458: *10606 connect() failed (111: Connection refused) while connecting to upstream, client:
can you please help?
