Port Forwarding error "We are having some trouble"

@doesnotmatter_​ I received my XB7-T today and will be making the switch tomorrow.  I will let you know.  However, I would be very interested to know if someone has been able to create new forwards before I take the leap.

@doesnotmatter_​ 

I have XB6 and can’t set up ports. Was planning to go get an XB7 next week to see if that would work. I honestly don’t think it will. It really seems like a user authentication problem on their back end and it’s affecting a lot of people but not everybody. Of course, this could all be avoided if they would just let us set up port forwarding on the Gateways admin page, especially since we’re paying a monthly rental fee for it.

@Jerry_C82​ What model gateway do you have?  XB7-T?

I have a XB7-T and am experiencing the same problem. Is there a problem with this model? Are there any work arounds or can I buy another router to fix the problem?

@user_20a5bd​ 

I don’t think the problem is specific to the Gateway. It is affecting people with the XB6, 7 and 8. It seems to be a user authentication error on Comcast’s backend. Until they fix it, we won’t be able to do any port forwarding setup or edits. You could put the gateway in Bridge mode and connect your own router.

I have the XB7, model shouldn't matter, I can almost guarantee that it's the Xfinity proprietary software that they have that prevents changes from the router itself. I've restarted multiple times, factory restart also, no fix. This was an old port I had set up and interfered with the current port I had, I was only able to delete the current one and get an error when trying to delete the old one.

Hello and thanks for reaching out @Jerry_c82. I am sorry to hear you are having port forwarding issues. It has been a couple of days. Are you still having issues, or where you able to get this resolved? -Aaron 

@user_5aa3c9​ Thanks for the follow up. Do any of the port forwards you were able to set up work still? If so I guess it could be used as a quick bandaid solution, I.E factory reset, open all ports, and repeat when you need it. Super terrible but better than nothing at all? Either way, [Edit: Language] to hear it didn't last.

@user_91ee02​ Yes.  All of the ports I opened continue to work.  So at least I have that. :)

@user_91ee02   Not sure what is causing this, but my port forwarding functionality is back today.......  ???

@TheOfficialZero​ Would love to see this. Makes zero sense why we can't port forward our own machine locally, and rely on some broken app.

@TheOfficialZero​ Id be very interested in this! 

@user_70f1dd​ Just curious, when you did the factory reset did you then do a manual set up of your modem/router?  This is what opened port forwarding for me.   

I'm in the same boat:  "We Encountered an Issue.  If the problem persists, check back later."  I too have working 'forwards' and don't want to reset my router without a proven path forward.

It appears a factory reset is not always the answer, but I was curious - What do you mean by "manual set up" ?

Thanks!

(I'd buy my own modem/router, but fiber should be available soon, and I plan to switch.)

Yeah, same problem. I've got working port forwards, so I don't want to reset, and it seems that even resetting doesn't really get the issue resolved. The only advice I can offer anyone looking for port forwarding services is to use a VPN (like Hamachi or, for gaming, I've been using playit.gg) while they get this resolved, or switch to your own hardware if you're able to. But that's really just a workaround, and I've seen posts where the bridge mode doesn't even work...

The only place you're going to get consistent support service is the Comcast_Xfinity reddit page, it's been a few weeks now but they say the backend team is well aware and supposedly working on a fix. They're professional enough to respond and keep me updated on the progress every day as well. They just have not given me a time frame, which is disappointing. But maybe if more people post there, they'll elevate the priority or something. Either way, good luck all.

@Will-R​ When the router is reset to factory, you will need to use the xfinity app to reactivate and set up the router.  At that point you have a choice to bring in the settings stored on your xfinity account, or set it up manually.  If you choose to set it up manually you will need to create your wifi SSID's from scratch - and (in my case) reset the DHCP ip address range.  I always have my router ip set to 192.168.1.1 and after choosing to set it up manually, it was set to 10.0.0.1.  I had to go into the router admin page and reset that to my preferred settings.  It is my thought that by not importing in old setting, the block on port forwards goes away.   My port forward function stopped working once since the reset, but came back within a few hours.  The port forwards I set up after the reset have continued to work since I set them up.

I bought and installed an Arris T25 and TP Link AX5400 router. Port forwarding works fine now and the setup couldn’t have been easier. I returned my XB6 and am now saving $13 a month on bill. Not sure what to do with Xfinity pod. 

@user_761396​ turn off advanced protection

@Will-R​ I'm at work but I saw this notification at lunch, just checked the website and the app, and you're right. Finally! Now let's hope they extend this act of kindness and let us keep the website interface. Either way, hoping this resolved for everyone. Haven't had the chance to check if the forwards work, but the interface seems accessible/fixed.
