Hello. I have begun receiving the following error messages (below) when attempting to access all of my localhost-based Joomla development sites that are located on the same device that I am trying to access the sites with, (no LAN or secondary devices involved).
In Firefox: "The connection was reset"
In Chrome: "This page isn’t working localhost didn’t send any data. ERR_EMPTY_RESPONSE"
Previously, these sites have operated properly. However, after attempting to open them within the MAMP (v. 5.6 and 5.4) environments after a several month hiatus, I am getting these recurring messages. This is true on both the Visitor & Administrator sides of the sites. I was able to update one of the sites after multiple attempts to Joomla v. 3.9.14, with no effect on the error messages. Pages on the visitor side will sometimes load after several attempts, but the administrator side will only load the 'Control Panel' or 'System Information' pages after multiple attempts.
Can anyone offer any direction on what is going wrong and suggestions on how I can fix this? Thanks!
