A linode VPS, wordpress and seafile installed on lnmp, letsencrypt ssl configured on nginx.
A strange phenomenon:
If the SSL configuration is wrong (for example, the path is wrong, or the SSL file configuration is wrong), or the accessed URL is wrong.
I can’t ping the VPS server from my computer, and neither the vps nor the website can be accessed.
It will automatically recover in about 5-10 minutes.
Currently, I have changed lnmp versions (php and mysql versions), changed linode computer rooms (including IP addresses), and changed linux distributions (centos 6.5 and fedora 23).
I don’t have much experience, please help me. .
