[SOLVED] nginx Bad Gateway after idle

[demian.smith]

I know, necromancing is not en vogue - but the issue is back.

Exactly the same as before, including the startup user "pi" and the local user "rpi" and multiple threads for php...ssh works as usual, but the gui gives the "502 Bad Gateway" :/

The "weird" thing with php is that before the reboot systemctl gets "stuck", after the reboot I get

This is a bog standard install, only changed the hostname via gui and set a static IP. I have 38379 tracks, so moode should be able to handle the e collection based on what I read here in the forum.The external disk does pass smartctl, so there's no problem there I believe.

Maybe I have to replace the SD Card?
