I installed Let’s Encrypt SSL certificate only for my hostname successfully, but it works only 3-4 hours. After that i can’t login to my DA panel and phpMyAdmin panel too.
I change ssl=1 to ssl=0 in directadmin.conf and restart DA and change it again to ssl=1 and https works again and i can login into DA.
I installed certificate by this guide:
but changed this line:
./letsencrypt.sh request your.hostname.com 4096
./letsencrypt.sh request_single your.hostname.com 4096
because this error: Challenge is invalid. Details: DNS issue: NXDOMAIN looking up A for www.mail.myhostname.com Exiting …
I’m using non-standard port for DA instead of default 2222.
Please help me solve this issue.
