How to solve error EOF connecting to InfluxDB?

Question

I'm using InfluxDB 1.8 and Grafana through docker for months without any problem until today. Suddenly I can't access InfluxDB. The error I get is:

Failed to connect to http://localhost:8086: Get http://localhost:8086/ping: EOF
Please check your connection settings and ensure 'influxd' is running.

Docker is running, it's checked. Some tests I did were to restart docker, change the port, run InfluxDB without docker, and finally try it without the databases (all empty).

It only works when I delete the databases, but then I lose all the content. I thought that maybe some file is corrupt but I don't know which one. Any idea how to fix this error?

Thanks in advance

EDIT: Well, I finally deleted the corrupted file but the EOF error persists. However, now if I run the verify tool there are no broken blocks. Maybe it is because it cannot be deleted directly and there are references to its content somewhere?

If you suspect that the files might be corrupted, you could make use of following tools to verify the integrity of TSM files:

influx_inspect verify -dir <storage_root>
