Uncaught Predis\Connection\ConnectionException: Error while reading line from the server. about phpredisadmin HOT 6 CLOSED

It basically says it can't connect to tcp://host.docker.internal:6380.
Make sure Redis is running on the same machine on port 6380 outside of Docker.
If you run Redis in Docker as well you'll probably have to use docker-compose to start both inside the same network and use the container hostname to connect to instead of host.docker.internal.

Thanks...
First off, I'm running through an ssh tunnel, so Redis is on the other side of the tunnel and exposing port 6380.
Second, the following works to start rediscommander thru the tunnel

docker run --rm \
  -p 8181:8081 \
  -e NODE_TLS_REJECT_UNAUTHORIZED=0 \
  -e REDIS_HOST=host.docker.internal \
  -e REDIS_PORT=6380 \
  -e REDIS_TLS=true \
  -e REDIS_PASSWORD=$1 \
  rediscommander/redis-commander:latest

so I can't figure out what's causing phpRedisAdmin to fail... I'll keep trying things, but any insight you have would be most appreciated.

Could it be that you have the SCAN command disabled? It is trying to execute this command and the error happens when receiving the response. Otherwise I have no idea how to help you further.

Side note: What is the benefit of using phpRedisAdmin over redis-commander? It seems like redis-commander has more features and is being actively developed.

Sounds like you have a lot of keys in your Redis. These kinds of admin interfaces are more for smaller instances or for during development.
To maintain some production system with a lot of keys I would always just use the CLI interface.
I heard some good things about https://www.redsmin.com/ in the past, but I have never used it myself.
