I use apache. And have a website. But when I try to open it by browser I get
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

What may be the problem?

Most likely whatever script your running and is failing with premature script headers or whatever, my guess would be that your apache webserver is setup to use custom error pages but could not find the page to display for error 500..

I have found
Address already in use: make_sock: COULD NOT BIND TO PORT 443
in /usr/local/apache/logs/error_log

That would have nothing to do with the error your getting.

I googled a little about your problem. Did you change the error pages from you apache?

No, I did not change error pages.

So.. ummm... any more information you want to provide? It's only a guessing game for us unless you give us more information, more clues to what you've tried, changed, installed.. etc?

I have modified /etc/passwd a have changed password for user postgres (that run postmaster - postgresql process).
I suppose after that my site began work incorrectly.

I did not execute any other modifications in system. So if it isn't postgresql problem it must be apache soft falt. But I do not know how to treat apache error_log information.

I see lines like this in /apache/logs/error_log now

And the error I have indicated already (Could not bind to port 443 SSL) encounter for one time. Need I look at ssl_log?

I have observed that my site was stopped to dump in
/pgsql/backup since 18.06.05 also.
