I can’t access the site externally from IIS on docker

I have installed IIS on docker, disabled any firewall and configure no-ip for access externalLy, and finally configured no-ip on my router with port fowarding…
I have configured iis and congirured local port 91 to 80 container port…
from local ‘http://pincopallino-no-ip:91’ compare correctly the default iis page, but externally network I get ‘err_connection_timed_out’….

Corrupt .htaccess file

My site was running well last summer. But today when I tried to make updates in the wp-admin section, I got lots of 403 errors on all PHP files: load-styles, load-scripts, edit.php, media-new.php, etc… The interesting thing is that the front-end of my site has no problems.

What are best practices for configuring a server for WordPress sites?

I hired a sysadmin to set up a VPS server for me and, unfortunately, it looks like things were not set up correctly. When trying to install and update plugins, I run into permissions errors all the time. WP Super Cache is the main issue as it causing my readers to run into 502 errors. Currently, my site does not load pagination (no Page 2, Page 3, etc..).
