XSRF token invalid

"Invalid or missing XSRF token. Please reload the page and try again."

I get this error quite frequently when returning to the admin panel after viewing comments on the site, I think there may be a conflict as my site and the admin panel are hosted on two different domains. I have already tried manually setting xsrfSecret in the secrets.yaml file.

If I clear cookies for the admin panel, I can log back in, and I'm able to perform admin tasks again for a while.
