Chrome "Connection Reset"

[fpolli]

I have a FrankenPHP-Laravel Octane set up in a docker container that I am trying to test at localhost. A couple of requests made it to Octane and responses were served. Then I tried to click a link on my test welcome page that wet to another page and got "Connection Reset" from Chrome. I entered the url of the second page into the address bar, and it was served. The Octane log reflects these successful requests. However, since that last success, every attempt to browser to localhost produces the same "Connection Reset" error from Chrome and nothing shows up on the Octane log. I'm guessing the request is not even getting to Caddy. I have tried restarting the docker container and clearing the data in Chrome.

Chrome also gives me the "your connection to this site is not secure" warning.

In case the info is helpful:

Laravel .env values of relevance:

OCTANE_HTTPS=true

I changed nothing on octane.php config.

Octane status check shows Octane is running.

This is expected since you cannot be the authoritative owner of localhost.

every attempt to browser to localhost produces the same "Connection Reset" error from Chrome

This sounds like a networking issue. You can double-check this by issuing a request from inside one of your containers to verify that the request completes successfully from inside the network.

Without getting into packet captures and routing information, have you tried simply rebooting your computer?
