IMAP node not working properly on self hosted

[Saad_Jawaid]

Hey there,

IMAP node is not working properly over self hosted version.

When I am trying to create credentials over IMAP node it not verifiying and it saying connection time out but i have tried to check the connection inside container and used telnet and openssl and its verified and connected.

Need guidance.

Thanks

best regard’s

It appears that you instance is not able to connect to imap.titan.email.
Are you using self-hosted or cloud n8n?

Ah nevermind, you said you did check from inside the container, which answers my question. Could you share the outputs from inside the container?

[Saad_Jawaid]

Its a self hosted version.

inside container when I have used OpenSSL for checking connection with imap.titan.email its says connected and dnslookup also seems to be showing fine.

Ok, I tried your server and your username in my environment, and I get an authentication error, which means:

• the server is reachable
• the account is correct

So this must be related to your environment. Any proxies configured for n8n?

[Saad_Jawaid]

Yes i forget to mention its working just fine with cloud version.

yes on my instances nginx is the reverse proxy but on my local i have only forwarded port via ngrok to make it https.

[jabbson]

I was referring to outbound proxies, for the traffic going out, not in.

[Saad_Jawaid]

No there are not any outbound proxies configured on my side.

Another thing which you could try to see if this gets us any further with troubleshooting:

• try to put in the IP address in that field, this is not going to get imap working, but will help us understand whether there are any issues with ipv4/ipv6 resolution mismatch
  • 3.208.130.184
  • 3.209.185.152

that is instead of imap.titan.email
