TheWormsUnited didnt fix it
aapanel wordpress 502 bad gateway
norge mmm that is really strange. How about removing the php or remove version and replace for another version have you tried that as well my friend?
TheWormsUnited yes i tried removing php and installing another version several times.
TheWormsUnited i took a screenshot. i managed today to get php 7.3 back installed, however it wont upgrade to newer 7.3 php and the php service says stopped.
norge try to hit Fix button on your top navigation, then go back to your php app and start it again.
TheWormsUnited steps taken upon what you suggested
- clicked fix panel
- update php, gets done and says update still. also back to error php service stopped even tried fix panel again.
is there a way to manually update php to even 7.4 via ssh and have to show latest in panel?
it seems fresh install of aapanel does not install php 7.4 either, so something is wrong with getting latest php 7.3 update not just php 7.3 and also something wrong with 7.4
TheWormsUnited with last reply, even tried updating php without vpn enabled
TheWormsUnited with the last 2 responses i also tried apache installed but i got error loading page like with nginx installed. so i can only use openlightspeed
norge is there a way to manually update php to even 7.4 via ssh
Yes! Its recommended? No. Why? You might break the aaPanel doing changes on the system.
Perhaps @aaPanel_Jose can give us a "hand" in this issue.
@aaPanel_Jose can you read my replies in this thread
norge
Hello, you can send the panel login information to jose@aapanel.com, I will arrange time to check the php problem for you
aaPanel_Jose hey i sent email last night did you find a solution?
norge
Sorry for my slow response, I just tried to check for you and found that the panel information you provided can no longer log in
aaPanel_Jose huh whats that mean?
norge
I mean, has your panel URL address been changed?
2 months later
I aslo had the error with 502 bad gateway. I did some crazy deinstallatzions of PHP and Nginx.
I fixed my error by switching the PHP version for each website to pure static. Then i swapped back to the php version i installed on server. It kinda resetted the website php settings and the site was working excellent again.
Posting here because I was searching so much for a solution maybe s1 will help it 2 
Greetings from Germany best Panel love it ^^
