Spotify Login blocked by router

[Raptoreverdark]

Hi,

I'm on Three mobile broadband using the Huawei 4G B535-232 router. Recently, I've noticed that I can't log in to Spotify on the mobile app. I know it's a router issue as the issue is not present if I use a different WiFi network. I read that the router could be blocking the ports to Spotify's severs, however, the router settings are not available (On my router, I see the message, "Some features are unavailable in CLAT mode". I think this must be due to a firmware update from Three, as previously I used to be able to open ports on the router.) Just wondered if anyone else is seeing this issue and if there is a workaround? Thank you.

This is also happening on my Router Huawei B535 since start of November. Long delay when starting Firestick TV and certain apps ob phone slow loading or not atall. All work ok on phone when use O2 mobile date or other three router (which is newer). So any help would be appreciated.

I have spoken with Three Customer Services Technical Support team. They deny blocking any services and have basically given up trying to fix the issue for me. Maybe try reporting it and see if you have better luck than me 👍

That sounds like standard practice - if there weren't enough Xbox GamePass Subscribers complaining on various forums online, along with news outlets getting involved, Three would never admitted it was their error and would never have fixed it - Three weeks they accused and blamed customers and Microsoft.  I also recall there was a month long Netflix outage two years ago that they denied for weeks until they had to give in due to the bad press they were receiving.

The fact is these are basic schoolboy errors that could have been easily fixed by just checking their systems.

I fixed my issue by changing the apn to three.co.uk as per this thread:
https://community.three.co.uk/t5/Broadband/FYI-IPv6-Prevented-VPN-Connection/td-p/14851/page/4

Not only has it resolved ALL my issues, but broadband is significantly faster with lower latency.

Three are indeed blocking a number of services on their 3internet APN - during the switch to IPv6 for 4G Home Broadband customers Three have made a number of configuration errors that they are refusing to acknowledge and their engineers will only agree to look into once enough complaints have been made online.  I have had no access to Internet banking, Spotify and my children have rarely gained access to Roblox with consistent errors and disconnects and logging into EA gaming services have been non existent of server errors and disconnects - This is Three standard practice judging from historical issues -  e.g. over a month long Xbox live and GamePass download block which Three Tech support and engineers denied and blamed Microsoft until week three of the debacle - which Three eventually admitted was an error on their side.

Not only this but they are now denying their customers, such as myself access to advanced features in their home B535 routers, such as adding my VPN to the router which would allow me to temporarily workaround Three's calamity.

The only option is to change your APN to three.co.uk - this will give you power back over your router settings and full access to the internet but we should not have to change our APNs as a backup because the primary Home Broadband APN is unusable due to mismanagement.

Think the Spotify issue might have been a temporary glitch, but still no longer possible to change port forwarding on this router?

Hey @Raptoreverdark,

Sorry this issue seems to be a new one, but off hand  I have a couple of ideas.

Check in your router settings to make sure the APN shows as 3internet as it may have switched over to three.co.uk which is for phone SIMs, this may be stopping port forwarding from working.

I'd also check if there's options for IPv4 and IPv6 and test this on IPv4 only.

Let me know if this seems to help.

Hi Jonathan,

Thanks for the reply. I already checked the APN settings on my router and it's set to 3internet. I cannot find any setting relating to IPv4 or IPv6 as I think this has been disabled due to CLAT mode. Plus I'm not even able to change the DNS settings on the router, so I have downloaded 1.1.1.1 (a free DNS resolver from CloudFlare) from the Google Play store and this fixed the "no internet" issue with Spotify.

Hey @Raptoreverdark,

Thanks for getting back to me. It definitely seems to be a new issue, but I'll see what I can find out. There's no options for CLAT mode on/off in the actual router console? Just references to this disallowing changing other settings?

Thanks,
Jonathan
