Issue 502 nginx panel error

[mikels]

When I run Plesk migration, I get a 502 nginx error in the panel, I just have to restart psa and it works again, but I would like to be able to fix it.

In the error log I get the following

tail -f /var/log/plesk/sw-cp-server/error_log

146574 recv () failed (104: Connection reset by peer) while reading response from header, request: GET / admin / module / list HTTP / 1.1, upstream: fastcgi: // unix: / var / run / sw-engine. sock:


I have tried the following

File Manager in Plesk shows 502 Bad Gateway: upstream sent too big header while reading response header from upstream response-header-from-upstream

I have all the micro-updates made, I have also modified the following

cat / etc / sw-cp-server / config | grep 'fastcgi_buffer'
fastcgi_buffers 128 2048k;
fastcgi_buffer_size 2048k;


I have tried the following

Plesk shows 502 Bad Gateway error after upgrade to Plesk 12.0.18

I have the latest version of sw-mariadb-client

dpkg -l | grep sw-maria
ii sw-mariadb-client 1.0.0-debian8.0.15080311 amd64 Mariadb client library


I have tried the following

Plesk shows 502 Bad Gateway error after login: sw-engine-fpm general protection ip:7f31fa131611 sp:7fff8df6d9d0 error:0 in librdbmspp.so.2.0 sp-7fff8df6d9d0-error-0-in-librdbmspp-so-2-0

I do not have librdbmspp

I do not know what else to do
