Getting "The resource you are looking for has been removed, had its name changed, or is temporarily unavailable." if url length is more than 4096 chars.

When I hit my app url with query params containing encrypted values (of length more than 4096) it is giving the error:
"The resource you are looking for has been removed, had its name changed, or is temporarily unavailable."
And in network tab, i can see code 404.

If url length is within 4096, it opening perfectly.

I need confirmation and resolution, if the url length is the reason of this issue.
