I use Nginx & Apache, now there is a strange problem, the website is frequently inaccessible, Chrome shows ERR_CONNECTION_RESET, I checked the error log, it shows as follows, how can I fix it?

I've tried rebuilding the server, and reinstalling SSL, but it doesn't solve the problem. I also tested the SSL certificate using the tool and the key and certificate match.

First:  Make sure that you have A records pointing to your server for cpanel,webmail,mail,ftp.   

In CWP, goto WebServer Settings -> SSL Certificates

Find your domain, and click on services, and check all of the services.  Hit save.  If it pops up an error, report that back.  If it goes green, then those errors should disappear.

But I don't need these subdomains, so I didn't add A records for these subdomains.
In addition, my mail is the purchased google enterprise mail, it needs to point to the A record provided by google

Then you can safely ignore the errors.  CWP creates them by default, and uses the ssl cert for them.

But my website is often inaccessible, Google Chrome shows the error code is ERR_CONNECTION_RESET

There is error in the log: AH00492: caught SIGWINCH, shutting down gracefully

Is this error causing the website to be inaccessible?

if it's constantly restarting, there can be numerous reasons.  Check /usr/local/apache/domlogs/  and go through the error logs for the domain in question to see if there are any explained errors.   

SIGWINCH is the code for something like the window being resized on linux, as it's not something common on a server install.  In any event, running it from systemctl should not be causing that issue.

There are no other errors found in the log, it seems that I have to reinstall CWP7

Don't reinstall anything.   We can work out the issue.   

Is your site high volume.  You may need to adjust the number of MBM workers.  Take a look at this article:

I have been getting the same errors on my servers for many years.  It's annoying and no one wants to fix it.  But it doesnt seem to have any adverse effects.
Listen to everything Pixelpadre says.
