Impossible to renew certificate for synology NAS

Hi Sahsanu

Yesterday I changed my synology settings, so that trafic on port 80 would not be redirected to https:443. Just to try to do something. Now I switched back, and I assume, that is the cause for your different results for when you checked the domain?

I have no idea what nginx is, so I don’t know where to find the nginx file?

I will try to do the ls command later today, and post the results here.

Many thanks again for your time!!
