-----------------------------------------------------------------
Hi Simon,
i already tried the steps - disabling the encryption helps. The encryption
handling should really be fixed.
also the sides work perfect a long time before they crash permanently with this
error - this doesn't look like a configuration error.
if something (which causes this error) changes at the client, the server should
be able to handle this.
Is there a security risk when the encryption is disabled and the state is saved
on the server instead of the client?
regards
