A user reported the following problem when attempting to visit

The requested URL could not be retrieved

While trying to retrieve the URL:

The following error was encountered:

* Read Error 

The system returned:

(104) Connection reset by peer

An error condition occurred while reading data from the network. Please retry your request.

There are no other issues reported by any other users, so it may be an isolated issue. Could anyone give me any suggestions as to how I could investigate the problem further or find a solution?

The message means that the connection was dropped on your side without returning the expected data.

See if you can correlate the time to something like a server restart. Eg, if you're using Apache, look at using { apachectl graceful } rather than { apachectl restart }; the former lets existing connections finish their work, the latter is more abrupt and might result in that message. Does your log rotation system involve a server restart, for instance?

Check your server logs, looking for that address. Check dmesg, to see if a component of your server crashed with a segfault.
