Hey guys, Maybe this one was answered and dealt with but I can’t find it here. Therefore, posted mine one, hoping someone could elaborate what is going on: (unknown): did not find expected key while parsing a block mapping at line 40 column 3 -e LANG=en_US.UTF-8 YAML syntax error. Please check your containers/*.yml config files. Thanks,

is this a fresh install or you’re using an old yml to build a container?

it is a fresh install and done it several times but this is the first time I have this error :no_entry_sign:

Can you share your redacted app.yml?

Yes, the entire file and redact any sensitive information.

This fixed the error and app went all the way but with another error not launching the discourse! I scrolled up to see what was there as it said but had nothing mentioned except port 6379 is not opened and this: Though the "loose" option was set to "false" in your @babel/preset-env config, it will not be used for @babel/plugin-proposal-private-property-in-object since the "loose" mode option was set to "true" for @babel/plugin-proposal-class-properties. The "loose" option must be the same for @babel/plugin-proposal-class-properties, @babel/plugin-proposal-private-methods and @babel/plugin-proposal-private-property-in-object (when they are enabled): you can silence this warning by explicitly adding ["@babel/plugin-proposal-private-property-in-object", { "loose": true }] to the "plugins" section of your Babel config. Though the "loose" option was set to "false" in your @babel/preset-env config, it will not be used for @babel/plugin-proposal-private-methods since the "loose" mode option was set to "true" for @babel/plugin-proposal-private-property-in-object.

I’m not sure this is significant but I’ll fresh re-install discourse first and my other control panel to host my other pages :saluting_face: I’ve promised someone here to report if things went right when installing discourse and other sites on same server and been trying hard to get it right but it isn’t happening yet :notes:

It looks as though you’re trying to publish on a different port. Are you trying to put Discourse behind a reverse proxy? I would revert the expose statement for now and try accessing over 80 first if so. If you’re just trying to install discourse on something other than 80/443 for direct access please note that this won’t work and isn’t supported.

Affirmative Stephen, I was doing that but I decided to install discourse first and play with other stuff next…! I’m almost there with the fresh installation as I type :cyclone: I should reduce caffeine intake :cactus:
