Issue with launching with Docker

[bclaudio08]

Hi,

I am trying to launch via Docker and http://server-ip:8000/ but when I do I get two errors:

Warning: session_start(): Cannot start session when headers already sent in /var/www/html/index.php on line 48

Warning: Cannot modify header information - headers already sent by (output started at /var/www/html/src/Config.php:60) in /var/www/html/index.php on line 72

Tried Googling around to find a fix but all my attempts were unsuccessful. Any direction or assistance is greatly appreciated.

Thanks

Does it work without docker?

It is working with Docker for sure - that is exactly how I use it. But from time to time I get this on "Main" interface load and sometimes on "Blocks" tab:

I'm using alpine + nginx + php-fpm

Update: Those warnings are no longer a thing when using alpine 3.18 and the latest version of php 8.2.8 🎉

Update2: I suppose I spoke too soon. After leaving the service running for some time, I encountered this issue upon opening the BNM:

When I tried to refresh the page, everything is back to normal.

These warnings and deprecated messages are popping up on the Main page from time to time:

I'm trying to figure out why this is happening, and it exhibits very inconsistent behavior, making it hard for me to replicate. Does anyone have an idea what is going on or a solution for this??

I wonder if this related to your tor usage. I am wondering about the 4 Unknown Peers. I never have these on my server.
Do you have peers that you are only connected to via TOR?

[k0gen]

Yes, I do.
I have also noticed that those long names do brake the layout.

[Mirobit]

Okay, that helps a lot.
It is whitelisted peers and onions peers that cause the exceptions. There seems to be a bug with caching the geo information for whitelisted peers. Getting the geo data for tor peers can't work, but BNM still tries. Plus tor addresses need to be shortened.
Thanks for providing the screenshot. I will fix these three issues in the next week.
