Description
I have guacamode deployed with docker swarm
guacamole version: docker.io/guacamole/guacamole:latest
guacamoledb version: docker.io/mariadb:10.9.5
guacad version: guacamole/guacd:latest
I created those containers with previous versions, but now updated everything as shown previously, and now, on guacamole log i have:
