The issue you are facing:
Hi - I was unable to load the apps pages from the settings pages like normal. Spins for a while but just stays a white page. Looking in forums for fix I saw to add the https://api.nextcloud.com/v1 url to the config file. Before I did that I tried that URL in Fireflox and received an invalid security error saying the LetsEncrypt Cert on that server isn’t valid. I am assuming that’s the problem in my NextCloud install as well - it can’t reach the server.
Websites prove their identity via certificates. Firefox does not trust this site because it uses a certificate that is not valid for api.nextcloud.com. The certificate is only valid for www.nextcloud.at.
Then if I click for more details it shows:
Unable to communicate securely with peer: requested domain name does not match the server’s certificate.
HTTP Strict Transport Security: true
HTTP Public Key Pinning: false
Is this the first time you’ve seen this error? (Y/N): Y
Steps to replicate it:
- Go to app page in NextCloud - shows installed apps - but if trying to browse tool for more apps online - just shows white page.
- open firefox to see if server address is valid for https://api.nextcloud.com/v1 that’s shown in documentation as the default.
- Receive invalid cert alerts from Firefox.
