OSError: [Errno 2] No such file or directory

Hi!

I'm not super versed in python, so you'll have to forgive me...

Got things up and running, however I'm facing this error:

Exception in thread Thread-1:

Has anyone seen this before? Is this normal? Also, how do you change what IP the flask server is listening on? Trying to access the webserver from another device returns a "refused to connect".

Thanks!

Try to reboot your system. Or change the port from flask before you start autowx2.py https://github.com/filipsPL/autowx2/blob/72804c588a1d793e2b5f76471a67e55d0d7201ab/autowx2_conf.py.example#L149

Thanks for your reply, @SA7BNT.

Changing the port didn't work to get the flask server up - however I'm not seeing the error I was seeing before anymore. I think it's listening on localhost so it won't accept traffic on eth0.

Flask seems to be running in debugging mode - I'm not familiar with Flask at all, how do I take it out of debug mode?

[SA7BNT]

You may try to install lighttpd or apache2. Then point the autowx2 config to your page https://github.com/filipsPL/autowx2/blob/72804c588a1d793e2b5f76471a67e55d0d7201ab/autowx2_conf.py.example#L102 Maybe that will help you

[ChadOhman]

Thanks. Installed apache2, pointed autowx2 to /var/www/html, and nada. Manually copied autowx2/var/www/ to the apache2 web root and while that did create content, I've noted all of the referenced elements on the page have an extra / in front of them. I tried stripping out all of them but something doesn't seem right. I don't know if this is the solution.

Update: used nginx reverse proxy - I now have a functioning webserver! :) I'm going to go ahead and close this. Thanks for your help!

[ChadOhman]

Just kidding - I can't view the table - the hyperlink is pointed to http://server/table - not table.html. pointing to table.html gives me a 404 though the file exists in var/www/. Interesting. Polling is also returning a 400, pointing to /socket.io/?EIO=3&transport=polling&t=M-Tx-&sid=0a1ecc1616ab4fd2a2b78bba53099303... etc.

[SA7BNT]

OK. The config on my side is pointing at /var/www/ Take a look inside autowx2 there you will see a map var/www/ Inside this there will be your DashBoard. I just pointing symlinks to this map and all was running fine at my side.
