matrixsynapse: LDAP auth no longer works
FreedomBox testing 0.48.0
Matrix Synapse 0.34.1.1-4
I installed Matrix Synapse on an AWS EC2 cloud instance with a valid domain name and LE cert. I tried logging in on Riot as the FreedomBox user admin. It shows the error "Error: Problem communicating with the given homeserver. (M_UNKNOWN)" in the Riot web UI.
The following is the error log seen using journalctl -u matrix-synapse
