Nextcloudpi connection problems, port 80 blocked, using DNS validation

#1

My isp blocks port 80, so I had to use DNS validation. I ran the command:

certbot -d (my subdomain.domain.tld) --manual --preferred-challenges dns certonly

Files would sync for about a day, then I’d start getting connection errors. Restarting the raspberry pi would usually temporarily fix the issue.

Last night I changed the LAN address of my router so I wouldn’t get conflicts with accessing 192.168.1.1 through my router’s vpn on another network.

Here’s the output of sudo ncp-report:

I think I fixed it. I ran:
sudo certbot delete
