VxRail Configuration Portal - nginx Error - 400 Bad Request - Request Header Or Cookie Too Large
Hi,
I'm trying to access https://vxrailconfiguration.dell.com/getStarted to create a new configuration for a cluster deployment.
Unfortunately I receive following error when accessing the site:
400 Bad Request - Request Header Or Cookie Too Large
I already cleared cookies, used different browser, different client, different internet connection. No luck.
Any Idea what the problem is?
Thank you and kind regards

Hi,
Thanks for your question.
Is the client OS language set to English? I haven’t been able to replicate this issue from multiple devices and connections. You can manually deploy without it. https://solve.dell.com/solve/home/VxRail%20Appliance
Let us know if you have any additional questions.

I have such problems (exact same error message) for certain dell services when using Firefox as a browser. My solutions it to switch to MS Edge in those cases.
Ah... in case of vxrailconfiguration.dell.com also Edge isnt working. But the different was das Edge redirects to the login page where Firefox displays the error msg imeditly.
My Edge is configured to remove all cookies when closed the browser and firefox doesnt. I have 1000 dell cookies for sure.
Ok... its for sure a cookie problem. After restarting edge(which deletes all cookies and history) the login and accesing works.
Regards,
Joerg
