I use localhost to develop Wordpress websites locally but since upgrading to BigSur, I cannot get localhost to show my local websites.
My set up is MacBook Pro with Big Sur v11.4. I use MAMP software v6.3 for my local server environment I have tried to open local websites on Safari 14.1.1 and Chrome Version 91.0.4472.101 There's been brief intermittent success in an incognito Chrome Window and in Safari when I first tried to use localhost:8888 but that was only when I was able to use http and not https (when unsuccessful it redirects to https: and fails).
With MAMP running...
When I type 'localhost' in either browser - I get "it works!"
'https://localhost:8888' returns On Chrome: "This site can’t provide a secure connection localhost sent an invalid response. ERR_SSL_PROTOCOL_ERROR"
On Safari: "Safari can't open the page "https://localhost:8888" because Safari can't establish a secure connection to the server localhost"
I try to type in http only but it always redirects to https: in both browsers
When I use an incognito window in Safari - the website displays as expected but
In Chrome incognito - it returns "This site can’t provide a secure connection localhost sent an invalid response. ERR_SSL_PROTOCOL_ERROR"
It seems like it's https: causing a problem but I don't know if that's a correct assumption or how to fix it. Can anyone help to identify the problem and how to fix please as it's really impacting my ability to work.
I have asked Apple for support but as it's not clear where the issue lies they haven't really taken this on as their problem.
