How can we connect locally running n8n instance with WhatsApp or telegram or any other external option to trigger for our n8n workflow. As it is running on local host i have tried to deploy NGINX as reverse proxy but didn't work. Any one have done this as it would be great to use local automations without need to deploy it on cloud.

throw all of google app away and start over.. helped for 10 miutes Gmail problems- always giving me '"Unable to sign without access token (item 0)" i have set all the credentials and where I get the callbackurl like this 'https://<my url>/rest/oauth2-credential/callback' I can do the login so I guess that all should be alright? I can do the same with sheets and that seems to be working? But calender is also not giving me a correct response 'Unable to sign without access token' lost of where to look, somebody any ideas? regards, Michael
