http error 431 - Increase max header field size?

I'm getting http error 431 stating request header fields too large. Is there a way to increase the max size of header fields for jetty?

Issue is only happening with chrome while using reverse proxy authentication. MS Edge doesn't have the issue. I can resolve the issue for a minute by clearing cookies, cache, etc. but it comes right back.

Server logs don't show the header, just: org.eclipse.jetty.http.HttpParser - Header is too large 8193>8192. I assume that's not the actual size of the header, but rather it stops at 8193?
