I had this error and looked at it with the Javascript console and saw the underlying issue was a network connection failure. On a hunch I turned off the "Private Relay" feature on my MacOS system. That fixed it. So perhaps you are running a network proxy or VPN etc. which is causing this issue?

Can't update any profile pics/offline banner/channel banner etc. Please fix.

I cannot update my banner either, and it keeps saying "Upload Timed Out, Please Try Again... I just need to fix my offline banner.

I cannot update my banner. "Upload Timed Out, Please Try Again" even for an icon size image

Something is broken. None of the uploads work today. No profile pic. No banner. No offline screen. Submitted a ticket. Hopes aren’t high. Lol

I can't change any of my images today and I NEED my offline video player banner updated :(

Its 2022 and TWITCH ITS STILL A FRICKEN PROBLEM . Fix it. Your perfecly capable 🙄

I've tried uploading an image on three browsers, incognito/private mode, extensions disabled, on the mobile app (b/c I'm trying to upload a new profile pic too). Absolutely nothing works. Clearing the cache, restarting the browser -- every troubleshooting step anyone has suggested on the internet, I've tried it and I still can't perform the complicated, site-taxing step of uploading a couple photos smaller than 1MB.

Just shrinking the file size worked for me. I had a 6mb file and just used the resize tool in ms paint to rescale it to 50% and it worked first try after failing the previous 10+ tries.

Why would the devs make the timeout duration so short? This is just terrible design. ):

This problem happened to me also, all u have to do is decrease the size of the image, i know it says the image cannot exceed 10mb, but i tried uploading a 4mb image and it didn't, it only worked when i tried a 900kb image.

i got this same problem but i found out that it's just a visual glitch and if you refresh the page after trying to upload the banner, it works, even if you get the error

When is says upload timed out refresh the page and it works. I've been having the same trouble and refreshed the page and it uploaded

This error has been going on for years and Twitch hasn't bothered to fix it. everywhere i look to find a way to upload it without an error i get the same problem with different people. I know it goes as far back as 2016 cause thats the earliest I've found it on (/r/Twitch) Some have found solutions like going Incognito or deleting your history,cookies,caches,etc. I unfortunately have not found a solution and have even gone as far as emailing Twitch customer support with no reply. If anyone can help or fix the errors then please let me know. The errors i get are "Unexpected Error, Please Try Again" Now it doesn't say that it says " Upload Timed Out, Please Try Again" I can't fix it no matter what i do. Please fix it
