Hello,

First of all thank you for all your hardwork and support.

I use Mailcow email server behind NPM for about last 2 years with no issue. After the last update of Mailcow this April they require bigger cash size for the proxy host.

https://github.com/mailcow/mailcow-dockerized/issues/4537#issuecomment-1090126628

https://mailcow.github.io/mailcow-dockerized-docs/post_installation/firststeps-rp/#nginx

please help me how can I change this either in GUI or by updating config files.

Thank you.

I also had same problem. Added in NPM Advanced:

proxy_buffer_size 128k;
proxy_buffers 64 512k;
proxy_busy_buffers_size 512k;

It all works fine now.
