Hey I’m trying to set up HighLevel API.
I’m able to follow every step but when I log in in the platform I have the error ssl_error_rx_record_too_long in Mozilla and ERR_SSL_PROTOCOL_ERROR in Google Chrome in the URL https://n8n.agileadad.io:5678/rest/oauth2-credential/callback?code=cdec8b1530356335d706a44a8a51f2d81b1b2cc8&state=eyJ0b2tlbiI6IkZ1cW1XTXR6LTZJZGRRWXlmYll5dXpTYktMU3RZMlJNd1kzSSIsImNpZCI6ImtrakptTkJRT3lqRW1IUk4ifQ%3D%3D

The information is there! Thank you for your automated reply 
Hey @Federico_Quiroga_Diz,
Welcome to the community 
Most of the information is there, You have not included your OS or the executions process which is why the bot replied 
To answer your question your URL doesn’t look right to me, If you look at it you have the port in it still so I suspect you have set n8n_protocol to https and the host to your url but you have not set WEBHOOK_URL to https://n8n.agileadad.io, Can you try this and stop / start n8n and verify that the oauth redirect url has changed to not include the port then try again.
Thank you Jon, to be completly honest I don’t have a clue on how to do that.
My OS is Debian 12. How do I set WEBHOOK_URL to https://n8n.agileadad.io ?
Thank you again for your explanation and generosity
I checked in the /root/ecosystem.config.js and this is what I see
For what I understand the Webhook_URL si set to “
https://n8n.agileadad.io/”
Am I understanding it too wrong?
