   Thanks for the detailed reponse @nickva @kocolosk 
   
   This is what I could find out using your info:
   
   - When I disable the session auth plugin and use `couch_replicator_auth_noop` the log messages go away, replication continues working
   - When I have nginx log the cookies included in the request(s), I can see that a non-empty `AuthSession` is being included in requests coming from the CouchDB Replicator. Its value also does not contain whitespace or anything unexpected.

   For me to debug further, it would be interesting to know how I can further map these error messages to a request.
   
   If I look at the log messages I can see some identifiers like:
   
   ```
   [notice] 2020-01-13T09:35:41.390874Z couchdb@couchdb6.local <0.6072.1500> ce9077a0e1 some.hostname.example.com ...
   ```
   
   or
   
   ```
   [error] 2020-01-13T09:24:07.152363Z couchdb@couchdb7.local <0.8946.1807> -------- couch_replicator_auth_session : Could not parse cookie from response headers cookie_format_invalid
   ```
   
   but I'm not entirely sure what the `0.6072.1500` (or similar) and `ce9077a0e1` are all about?
