Began getting this error message when attempting to log in to Tranquility yesterday afternoon:

Bad Request - Request Too Long  
HTTP Error 400. The size of the request headers is too long.

When this began to happen, I had four active accounts on line and was cycling through a series of additional accounts to add game time and extract skill injectors. This is a common practice in the business of farming skill injectors. I’ve done this routinely without having any problems prior to today.

I have tried everything in the launcher’s Shared Cache tool (parsing indices, fixing permissions, verifying integrity) and also tried renaming cache files in eve/sharedcache and appdata/local directories in order to trigger new cache files, to no avail.

I am able to log into the Singularity test server with no problem.

Any ideas on what is causing this error and how to correct it?
