Android - Your IP has been blacklisted.

[hogan71088]

Hi All,

Anyone having this issue? Intermittent pop ups in the app saying your ip has been blacklisted but there's nothing in the blacklist.

Have noticed it across 2 or 3 systems now. V16sp5.

Not seen, is it when on 4G connection or even in wifi?

Same problem here, I have 3 facilities where users who have android phones are reporting these problems to me, in both sites the central is in the cloud, but no IP is in Blacklist

 

[hogan71088]

Cant remember if I've seen it on wifi but definitely on 4G.

 

[AWS2P]

When in 4G , is it always same location with same provider relay ? did you check which public IP you got while this occurs?

 

[hogan71088]

Issue seems to have disappeared on my own system but customers are still reporting the issue. Doesn't seem to be just 4G, it's definitely happening of WIFI also.

 

[AWS2P]

did you opened a ticket on 3cx side?

 

[Wilson Dario Maldonado]

I have in 3 installations of 3CX (2 in AWS and 1 on premise) they have failures because the softphone indicates that the ip was sent to the blacklist and when verifying there is no ip in the blacklist, it only fails in mobile data, with Wi-Fi does not show failures, when it fails with mobile data I close it 4 times in a row and it enters service, but after a while you want to use the application, the fault appears, also when you open it with Wi-Fi and turn off Wi-Fi and activate mobile data, it works.

Are you using the 3CX Global Blacklist? If so, turn it off and test.

 

[Wilson Dario Maldonado]

It is deactivated in 2 clients and in 1 it is active

I only report failures on android

 

[hogan71088]

This issue has started again randomly on a few systems we look after, can confirm we don't have the global blacklist option enabled.

 

[mcsphones]

Wow, I thought I was alone - this too started happening on ONE Android extension on ONE 3CX PBX we manage. Any thoughts?

 

[Wilson Dario Maldonado]

In my case I have 6 different clients with the same failure, but it only fails with mobile data in 1 single mobile phone operator, with Wi-Fi they do not fail me.
I already lost 1 client because the use of the softphone is essential at this time and the only 4 extensions never worked for the same failure

The ticket was escalated to development weeks ago
