Hi all, Webmin, apache and Letsencrypt worked fine a year ago and now I reactivated everything and I just don't get any certificates anymore. I followed tutorials, forum advices but whatever I do I have not any success. Please! Can someone guide me through this?
So I have the domain rootshape.com. And I have a subdomain cloud.rootshape.com on the same server with the same ip. The cloud.rootshape.com root folder is inside the rootshape.com root folder. Right now I disabled the port 80 virtual hosts so I have only port 443 for rootshape.com and cloud.rootshape.com but I cannot access them without certificate (SSL record too long error) After I went to webmin config -> SSL -> Letsencrypt, I tried all options in all combinations (DNS, apache matching hostname, etc.) Once I succeeded in getting a certificate for rootshape.com only, but I don't know what I have changed because it didn't work a second time. (I lost the certificate for rootshape.com right after I tried to get one for cloud.rootshape.com in a seperate process)
So, in my last try to get a certificate, I tried to get a certificate by folder for rootshape.com, cloud.rootshape.com and I got the error: cloud.rootshape.com challenge did not pass: Invalid response from http://cloud.rootshape.com/.well-known/acme-challenge/_9y9oRX8ZGhXSW3E87...
I have updated webmin to the most recent version (1.900) and I updated and upgraded and dist-updated everything else, too. I have Raspbian Linux 9 running. I hope so much that someone can help me because I have totally no idea what I could do.
