Additional information

Running BTCpay behind Apache reverse proxy.
Seeing errors in Docker nginx image similar to:

I'm not 100% sure what all the variables are setup correctly.
IMO, this issue is kind similar to #4162

Are you sure this is a bug report?

@agandix Hey, we just released this fix. Please update and let us know

[agandix]

Just to let everybody know - the fix worked!
I've updated via btcpay-update.sh to (b7b1fe1b832b67f9912b8350c7e6fe5c429cd208 added today, few hours ago) - and it started working right away (so, all the million settings, that I was trying to tune up for 2 days non-stop, were actually correct!). BTW the new version looks completely different!
Thank you!
