Weather Channel App - Malformed Headers / HTTP Error Code

I am having the same issue, it started Thursday 5/27/22. 

I don't know what you all are talking about.  Mine works fine. 

That's an obvious lie if I'm on this very specific thread.  The weird part is that half the time the conditions bar at the bottom will work.  It won't stay for more than a minute, but if all I need a quick gander at the temp, it may still work.  I hoped maybe it was just this cheap Roku device I have on my non-smart TV (which also seems to hate NBC), but TWC is down on my smart TV as well.

My solution is to use my phone.  When I first tried to download the app, I found that TWC only made one for Apple.  (C'mon, Weather Channel... I thought you were cool!)  Since I prefer my technology to be reliable and user friendly, I thought I might be out of luck with my Android.  The simple fix for me was simply to use my browser and go to TWC home page and save a link to it on my phone's home page.  Now I can get all the pertinent information, the stories, I'm pretty sure the shows, and of course the ads because I refuse to pay for apps.  For my needs, it works great except I sometimes like to fall asleep to TWC, and that's not something I can do on my phone.  Or, if it is something I could do, I haven't cared enough to figure it out.

I know this isn't a fix for the app, but I hope it will at least give you something to fall back on. 

I'm having the same issue as of May 27, 2022 and tried everything you mentioned. Can someone please response so we can get this resolved!

Adding my name to the list too. Mine also show the HTTP error as of 5-27-2022. Hope someone gets this figured out. We watch this channel every morning 

This issue us still happening.  Holiday weekend!  Will we get a resolution.   Tv, roku, twc app, spectrum, all re-updated, rebooted, re-re-everything to no avail.   Based on all other complaints of same issue, it is appear to be the site, or the app.  Help!

I'm having the same issue. We use Spectrum, and My husband depends on the Weather Channel App every day for his job, and is sooo difficult to predict now that the App is not working. This has been going on since 5/26/2022 Hopefully there will be a fix soon, like REAL soon!!! 

I too have the same issue on the Roku app. Uninstalled, rebooted, added the app back in. Still not working. Opened a support ticked with the weathergroup. 

Not holding my breath on the fix.

Same problem. Will monitor thread in case a solution is found.

Mine Began on 5-27-2022 as well. I have Spectrum. Tried firmware update of my netgear router, updating the app and re-starting Roku. No difference. Even my other Roku 4K stick does it too???

Adding my name to the list.  It started with me on 27 May 2022 as well; I'm using Verizon FIOS.  I've tried all the same suggestions as everyone else here and nothing has worked.  I wish someone could post an explanation as to what happened and tell us how to fix it!
