Docker error: Cannot start service ...: network 7808732465bd529e6f20e4071115218b2826f198f8cb10c3899de527c3b637e6 not found

I'm assuming you're using docker-compose and seeing this error. I'd recommend

docker-compose up --force-recreate <name>

That should recreate the containers as well as supporting services such as the network in question (it will likely create a new network).

shutdown properly first, then restart

docker-compose down
docker-compose up

I was facing this similar issue and this worked for me :

Try running this - docker container ls -a and remove the container id by docker container rm ca877071ac10 (this is the container id ).

The problem was there were some old container instances which were not removed. Once all the old terminated instances get removed, you can start the container with docker-compose file
