Megathread - "You are logged in but we are unable to access your account details" 

Hi @YWA123  give it a try now. There's a backend database configuration mismatch that I've manually set to fix. It should've been set automatically so I'm checking with the team on what caused it. Thanks for your patience!

Thanks for flagging @YWA123  this appears to be an issue on our end, I've asked our devOps team to triage it as part of a cluster of the same issue a few others are having. Thanks!

@ComcastJonathan  You fixed the problem. I am able to access my account information now. 

Thank you very much for the help.

Great news @YWA123, enjoy your services and Happy Holidays!

@ComcastJonathan 

This issue does not appear to be resolved. I'm trying to access my bill pay area and I get the same error messages as others in this thread.

I have tried 4 different browsers and also deleted alll my related cookies with no luck.

Please check if there is another issue (not the database thing).

Thanks.

Hi @Chas1971, your issue is also part of the larger database issue (we now believe My Account is reading a field in the database that it shouldn't be) so I'm at least setting the field to the correct value to enable you to sign in again, let me know if it's not resolved. 

Hi @ComcastJonathan ,

 My account access is now workingm thank you very much.

I hope you folks will be able to find a larger scale fix for the others having issues.

Regads,

Charles.

Yep, have been haranging the tech team all weekend, but they are back tomorrow during the weekday. Glad it's working now, enjoy your services!

I am having the same issue. Have tried different browsers and devices (nothing works). 

It seems like I'm having this problem because of moving my service. I can access my one account but not my primary. Could use some help, thanks! @ComcastJonathan

For god sake. Can anyone help? I can;t believe I already spent 5 hours with comcast and they can't figure it out my problem. I called yesterday and the rep said that he was going to modify the boot file on the modem and I think right after he did that, now my account is not showing as I am getting the error. "Sorry, This Isn’t Working Right Now"  I see here that Nathan had resolved the issue. @ComcastJonathan

Hi I am getting the same error message too! I just made my account..

Cannot access account information - error: “Sorry, This Isn’t Working Right Now”

Good Evening @ComcastJonathan I am experiencing the same issue im logged in however I get a error message when I want to see my bill details, Sorry, This Isn’t Working Right Now error comes up
