network is unreachable pop.gmail.com

[J_E_F_F]

Any idea why pop.gmail.com has become unreachable from within hesk as of late Dec?
I can ping it from my server (ssh) but hesk can not retrieve email via POP.

I use a google apps account, and I even tried a standard gmail account and I get:
Error: 101 could not connect to the host "pop.gmail.com": Network is unreachable

This has been a constant since 24 Dec 2014 that I just noticed today.

Still having same issue. Any ideas of google made changes that effect pop retrieval?

I was experiencing a "connection timed out" issue for a while, but after going to https://accounts.google.com/DisplayUnlockCaptcha and clicking "Continue", I was able to successfully connect on my local HESK instance. However, my production instance (on Bluehost) was unable to connect ("connection timed out"). Try using the DisplayUnlockCaptcha link above and see if it works.

Thanks, I sure was hopeful, but unfortunately that did not help. The same error remains.

[mkoch227]

Out of curiosity, what is the full log that HESK displays when the connection fails?

Error: 101 could not connect to the host "pop.gmail.com": Network is unreachable
Connecting to pop.gmail.com ...

I sent you a PM with credentials for my POP3 server. Let me know if you get the same response code, or if you get something different.

that worked fine, thanks for the test on a non pop.gmail.com account. Seems like google changed something that makes my install incompatible at the moment.

Works fine here. What is your PHP version?

[J_E_F_F]

5.2.17 and nothing changed on my end. Testing a non-gmail site worked. It just stopped working with gmail one day

If you can

Code: Select all

telnet pop.gmail.com 995

from the server and are using the correct Gmail POP3 settings then access to your account (or server IP) is most likely blocked by Google.

Unless you have ssh access and can use your server as a proxy to access and unlock the Google captcha from the server's IP there is not much you can do (Google security policies, not a HESK issue):
https://accounts.google.com/DisplayUnlockCaptcha

If you don't have ssh access your best bet would be to use a local SMTP server.

from SSH into server

Code: Select all

[root@www ~]# telnet pop.gmail.com 995
Trying 64.233.168.108...
telnet: connect to address 64.233.168.108: Connection refused

Well then it's either Google blocking your server or your server blocking port 995 then.

[J_E_F_F]

it was a firewall issue with my host. Thank you for the replies, the problem has been resolved.

It is because Google blocks sign-in attempts from apps which do not use modern security standards (mentioned on their support page). You can however, turn on/off this safety feature by going to the link below:

Go to this link and select Turn On
https://www.google.com/settings/security/lesssecureapps

Moreover google block an ip when you try to send a email since a unusual location, so, you can unblock in the next link
https://support.google.com/accounts/answer/6009563

and clicked in

accounts.google.com/DisplayUnlockCaptcha .
