Internal Server Error 400 / 403 (Clear your browser)

Thanks, this also worked for me. I normally use Chrome to access Zwift but needed to delete the settings on IE to rectify the issue.

Thanks Dave! this did the trick. Seems the problem is that the app cannot reach the update server. I hope they fix this soon.

Worked for me too. Thanks.

Shame it doesn’t fix it completely though, I still have to run through each step to open Zwift.

Another little annoyance is I can’t paste a password from a password manager, I have to type a long, complicated password in manually each time. I can’t be bothered to change the password, think I’ll just have to ride outside :sunglasses:

@Dave_ZPCMR 's instructions worked for me! Native Windows 10 app. Not using IE, etc. THANKS! :+1:

207

Worked perfectly for me. Thanks!

208

I’m not on windows but rather on Mac OS Catalina and I am getting the same message. I have done all the suggested steps and still to able to get in. Help!

Zwift is so horrible this time ! irresponsible, no solution !
There are so many annoyance from my staring zwift in Mid April: No title in activity feed (some have, some don’t have), error 404, error 500

Another one here, also screwed me. Reset all browsing data (a lot of which is data I wanted to keep).

Nothing. Still errors.

211

Yes, same problem here. It’s fine, just refund my subscription for the month and let me know when you have a service I can use.

You need to explicitly clean up INTERNET EXPLORER, not Edge or Chrome or whatever. Apparently Zwift connects to Internet Explorer.

For me this solved the issue

214

Still only working on phone, don’t fancy wiping safari cache on laptop so hoping it can be fixed at swift’s side sometime

216

If it’s a Win10 machine, it does have IE. Do a search (the magnifying glass to the right of the Win/Start button), search “internet explorer”, it will find it. You will probably get prompted to update IE, just ignore.

217

If you click on the solution at the top of the page you will see the full windows 10 fix.

218

This started more than a week ago. Obviously there’s a bug in the Win10/MacOS app, it’s not like all of a sudden all users’ cache got corrupted at the same time. Yes, there’s a workaround of sorts, but it’s a clumsy one at best (>90% of Win10 users are unaware IE still exists and is used regularly by apps on their machines).

So - any fix timeline?

219

Correct - opening IE and going into tools also works, you get to essentially the same place. But the posted solution has a lower risk of errors, less chances of opening the wrong browser or going “I don’t have IE on my machine”.

220

is there a way to fix this that doesn’t require me to delete all my internet passwords and data?

EDIT: I realized this is for Internet explorer so as long as that isnt the main browser (which why would it be) everything will be all good.

221

You’re actually using IE?

Or you’re on MacOS and using Safari?
