Hi,
I am using Caddyserver on a Ubuntu 16.04 server and I have 3 wordpress sites running under cgi. Everything seems to work except that random users tell me that there is a connection delay and sometimes in the middle of their visit, they get random disconnects. I have been able to verify each instance and it appears to be on the Caddyserver side. I have cloned the server and run it for a few weeks with Nginx and no problems. My question is to find out if there is a troubleshooting guide or recommendations on how to trouble shoot or track what is going on with Caddyserver.
It might be. I rolled back to 0.9.1 and it did seem like 2/3 sites were flying. One thing I have noticed is that it seems to happen every time I do something silly like type http://skills.ninja. (wordpress will redirect to www.skills.ninja. ( I can do the reverse) http://www.skills.ninja and have wordpress redirect to skills.ninja and the delays begin. Once the pages are cached, the problem isn’t a problem (of course) It’s that initial hit that just sits there. Also, it takes about 3-5 minutes after launching caddy before you see the issue. For the first couple of minutes, everything flies.
Given the likelihood that this is an problem with Caddy, the best place to get some movement would be to file a github issue at https://github.com/mholt/caddy/issues.
