Email or passwored change (gcm: tag doesn’t match)

Hello there,

I’m experiencing a problem changing my email address.
I enter the new adress in the “My Account” section after I logged in .
I get the first mail to the old adress and confirm it.
I get the second mail to the new adress and confirm it.
I get to the step where I enter the password and click on submit.
Just nothing happens, no matter what time I wait. It doesn’t take me further on. I also tried doing so with Firefox and Google Chrome, so its not a browserproblem.
Though, when trying to “reset” my password for the new mailadress it says there is a tranferring pending. So the system has the infos, just doesn’t seem to process it further on.
Additionally, since I tried changing the mail first, my TS profile can’t be completely loaded in TS, resulting in me sometimes havings no favourite servers, nor right on’em a.s.o.
When I contacted support on it, I was directed to this forum, so here we are.

I’d highly appreciate some kind of solution here.

Best regards
Kio Boid

I took us ages and this topic came up at least twice in a week and we absolutely had no clue.
But now we found out why this happens.

We assume very old client versions are used for these accounts.

Years ago (yes more than 5 years) the encryption was updated and the website requires that new encryption and fails because old clients still use the outdated encryption.

Solution:

  • Download and use the latest client:
    TS6 or TS 3.6.2
  • Login into that client
Be aware that this step may require your Recovery key!
So you might get your backup or create one in Client's account settings 
before installing the latest client.
  • Try again to change email or password

If above did not help go on with following

  • Change the password in the mentioned clients (to a different password)
  • Change your email if this was the initial problem
    ** Change the password back if you like

The client is the software to encrypt your account data.
It’s also to update the encryption on your account data in case encryption was done with old client and never was updated. That’s why you needed a newer client.

What you could try is to change the password in the client itself (it must be a different password then the current one). This updates the encryption again.
Then try to change the email on the website and change password back if you like.

That’s the only idea I got without looking into the account to see which encryption version your account has. I will do that after the downtime tomorrow.

Hello :slight_smile:

I am trying to change my email address. I do receive the validation link but once on the validation page, with my password informed, it stays stuck at “processing” after clicking “submit”.

I tried with two different browsers, without adblocker or shield, also using private navigation. I don’t really know what to do anymore as it looks like a bug from the website.

Thank you for your help!

Are you currently using a different account here in the forums?

From your registration date with your account this error should not appear? Only for older accounts, created 5+ years ago.

Anyways please try these steps:

I am using the same account yes.
After updating my password using TS6 client I still have the error (I checked, it is still the gcm tag thing).

It’s late here, I will be back tomorrow to try further using the other topic you sent before telling you whether I was successful.

Thank you again :slight_smile:

I initiated the process to change my email address and received the confirmation email to verify that I had started the request. I followed the steps in the email and was prompted to enter my password to complete the change.

However, after entering my password, the process got stuck when i’ve clicked on “change” (button spinning for more then 10minutes without message) and nothing happened. Now I cannot restart the process because I receive the message: “Sorry, there is already an account registered with this email.” And now?

This looks familairly like this issue:

Hello, so I have an older Teamspeak account (2014 or so, apparently this happens with older accounts) and I’ve had to change my attached email at least once in the past. I have access to the current email and the one I wish to change it to with no issues. But through the process when it asks me to input my password it gets stuck on a “Processing” loop, for upwards of 30+ mins each time I attempt to do it. I have reached out to support making a ticket, during which I did the steps in question (including attempting to change my password, same issue there; Processing loop) and was told as a last resort by the Support staff; “Please visit our forums and create a post so our technical support staff and community members can help you.”

For the sake of troubleshooting, I have tried this on 2 different browsers, once on my main browser with no extensions enabled, I have tried using 2 different email accounts as the new one, I tried to change the password before the email, and the support staff member had me download the Teamspeak 6 client to attempt to change a few settings there to see if it’d allow me to change the attached email. None of these have resolved my current issue and now I am at a bit of a loss. Thanks in advance to anyone who can help out with this.

I can see that you’ve initialized an email change but have not completed it yet.

Please check your spam folder or wait 48 hours until the currently pending email change request has timed out.

I had the exact same issue as you, stuck on 30+ minutes of “processing” for the final password confirmation in Firefox.

I finally broke down, refreshed the page in Firefox to cancel the “processing” status, copied the confirmation links from both email addresses (first the old, then the new one) into Microsoft Edge, was prompted to enter my password, and it went through immediately.

Not sure if it was Edge itself that helped or the fact that I always clear my entire browser history and cache after the rare occasion I do use Edge so it was a blank slate, but either way, maybe it works for you too.

Same, I’ve been trying this for years. I’ve just given up at this point…
Various emails, browser, internet connections. you name it.

Stuck on processing when I gave it a shot now again.

Can you check your browser console for errors? You can open it with F12.

@DestroyStuff can you also check it?

Hello, sorry for the delayed response, my hours are crazy! Anyway, per your request I do see a gcm: tag doesn’t match error much like Predonum did/does. Following the thread you posted very recently I logged into TS6Beta 3.4, changed the password, and attempted to change the email again (To a different email than the intended to check if it would work) it has not thus far, but I may need to just wait the 48 hours to try again (And probably log out from the site to refresh as well)
