I did some testing and it looks like Indian ISPs (Jio / Airtel Tested) are blocking Warp.
(126.96.36.199 DNS is working fine)
I installed Warp In a VM .
Connected Host PC to a VPN. Then tried connecting to Warp in the VM & It worked.
However when I tested with my real IPs provided by my ISPs, Warp failed to connect.
same thing happening to me also on pc. my isp is hathway, seems like they’re also blocking warp.
here’s the link to my results
All Indian ISPs, started blocking same day? I think, it can be something from cf, maybe.
So… I did some more testing with Wireshark…
Looks like all ISPs are blocking warp ports: 2408,1701,500,4500
for Warp Ingress IP Range: 188.8.131.52/24 (Port 80/443 works, only warp ports blocked)
This looks very much like government censorship.
or maybe i am thinking toomuch.
I’m also facing this issue. Jio went away for 8 hours for maintenance and then WARP stopped working for me.
Can we get anyone from CloudFlare WARP team to take a look here? To be just sure?
I did nmap scan, following ports are open.
21/tcp open ftp
80/tcp open http
443/tcp open https
554/tcp open rtsp
1723/tcp open pptp
8080/tcp open http-proxy
8443/tcp open https-alt
That’s just tcp though, none of udp ports respond. I feel, it’s data centres in India and not ISPs blocking, it’ll be bizarre, if they’ve started blocking it on same day? There is no court order or news for coordinated shutdown.
So i tried to connect WARP using Vi network.Its working fine…
Check the result
WARP uses the wireguard protocol, so its an UDP connection.
Indian ISPs have a track record of blocking stuff even if its not banned.
You’re right, need update from CF team.
I’m facing the same issue on a GTPL connection. At first I thought it might be something to with the update so I tried a few past versions of the WARP client and every time it says that it failed to register the client.
It is suspicious that all ISPs started blocking WARP all of a sudden.
Very suspicious, or are they using some russian backend, jk? Russia recently blocked Warp.
Hi sdayman. sorry just chat in. my bad. yeah actually i was burn out with the heavy thing to cover up. and im here as the beginner that try to understand about this new commnunication technolgy. hope you understand my situation. and about WARP not connecting on windows itself, i was confused about that. And i just install the DNS Changer and WARP 184.108.40.206 on my iphone7 and just use this laptop via thether. I was connect DNS changer with using 220.127.116.11, but on WARP, im not connect it. Is it different about the both of the app. I mean about the 18.104.22.168.sorry for noob question.thanks sir
Hi mr sdayman. Im just set that 22.214.171.124 on windows with the instruction. thanks about that.
At first, I also thought it must an ISP block but having read what you say here, especially the Indian case, I start to think that it’s not on the ISP side but it’s really on the Cloudflare.
Here is the topic I started a cpl days ago and there is an update in the latest message. I am copying it for your convenience, so we can continue the investigation in this thread.
Today I connected my mobile to the Internet via the other Wifi and other ISP, so WARP was suprisingly OK.
After that I connected to the Internet via 4G and WARP was OK again.
ISP in Belarus hierarchy is as follows:
Beltelecom - the 1st lvl, monopolist. - no block, WARP works fine for its clients.
CosmosTV - the 2nd one, lower. - the fail is here (I am their client).
Cell operators: MTS, A1 - WARP fails. I dunno which of the 2 ISPs are used by the cell operators but it seems to be CosmosTV from what we see.
After I got back to the CosmosTV network, my phone started to fail again with WARP and no way to make it work again. (I have no access to Beltelecom more to try a successful connection).
Russia has officially banned it, and I thought VPNs are illegal in Belasrus?
it is not working on GTPL Broadband, maybe there is an issue with isp or Cloudflare itself. All the servers are operational though !!
Seems to be working now on GTPL. Still not working on Jio.
Now working on every network. I guess it was issue from Cloudflare itself or they fixed it somehow
It’s working fine like before.Thanks everyone for your replies…
