Local Cardano GraphQL node Playground not respond (Dandelion)

Hello, I have a question about the local graphql node from Dandelion. Two days ago, the GraphQL graphics environment stopped working, but synchronization continues to work. When I look at the logs, the graphics environment stops after unsuccessful requests to http:\hasura:8080/v1/graphq. I use version 6.1.0 from GitHub. It often happens after the command ‘docker-compose ps -a’ everything is ‘up’ but not having access to the playground. Please if anyone else has encountered this problem tell me any solution to the problem! Thank you

Try:

docker container restart cardano-graphql

Alternately:

docker-compose down

Then:

export NETWORK=testnet && \
docker-compose -p ${NETWORK} up -d

Check the logs:

docker container logs -f --tail 10 cardano-graphql
