TVAPP-00148

After 6 days of receiving TVAPP-00148 and no resolution, I cancelled the streaming portion of my Xfinity service. Switched to YouTube TV plan Basic and it’s fast and you don’t have to change close caption every time you switch channels. I could not continue with no resolution from Xfinity and it appears this has been an ongoing problem with Samsungs updates. 

Same exact issue with me

Has anyone heard of a fix or what the situation is concerning Error:TVAPP-00148? 5 days and counting. I've reset everything and cleared data, cache, etc...I've been in contact with both Samsung and Xfinity and jumped through the hoops a dozen times. Anything???

Time to leave Xfinity and go over to AT&T. This is the last straw for me. 

Same here on both TVs we have. Samsung denies making any changes to tv firmware or there app ecosystem that would create this problem.

Having the same issues. Had to use a roku to watch live sports and news. Fix before NFC championship game next week please. The only reason to have cable these days is local sports and news. 

New day. New [Edited: "Language"]

Still get error code tvapp00148 trying to stream live tv,

AND NOW I get the same error code when trying to watch a show that is CURRENTLY RECORDING. I set my living room xfinity box to record Die Hard 2, currently showing on AMC, so I could watch it on my patio TV, the one without a box that I stream on, and it WON'T LET ME. I can watch previously recorded shows from yesterday or older, just not this one. I don't know if it because it is currently recording or if this means anything recorded today will be unwatchable. I did NOT have this issue before. Since this began, I could record shows from the box tv inside, and watch them from the 'saved' list outside,  even while currently recording. The Bucs starts at 3pm, and I'm seriously gonna be [Edited: "Language"] if I can't watch it. XFINITY GET YOUR [Edited: "Language"] TOGETHER AND FIX THIS!

I used X to @@Xfinity support the only reply I got was send a dm with personal information.

I'm getting the same error.  How did you fix it?

Just spoke to Xfinity , they now are admitting it’s their fault and have no time frame to fix 

Same problem my 2021 Samsung.  Glad I got on here to see its a general issue.  Hopefully resolved soon

I dug out my old antenna TV, and I can get the detroit lions game just fine

I just called after reading through the comments in this forum, as I am experiencing the same issue with streaming, and am receiving the same error code. The representative I spoke with stated that Samsumg recently did a firmware update, and there is a problem with compatibility, which is on Comcast's end. She indicated that they have received multiple calls, as this has affected thousands of people. She also indicated that Comcast is aware of the issue and the Engineering Dept is currently working on a solution. I insisted she credit my account since I'm paying for a service that I cannot utilize, and a $33 credit was issued to my account. Since I called, I was given an outage ID# and she told me I'd be notified of any updates with this issue, but I could also use the ID# to reference if I had to call back. So be sure to call and get added to the outage ID if you haven't already. Not sure I've provided any new info that's not already noted in previous comments, but hope this is helpful to someone. 

WORK AROUND! Saw previously but saying again to hopefully help someone. 

Set a recording for the channel you want, then go and watch the recording 5 sec behind live. Seems to be working after I tried TV reset, app uninstall and logout

Getting the same error message on our Samsung. Just started two days ago, before this the app/TV worked fine for months.
