Eventstore doesnt re-connect properly after disconnection

[kodeine]

So i put down eventstore (docker) while nestjs app is running, i re-run docker and eventstore is up. nestjs app says connected as well but in reality its not connected, see below.

the green ones in image, i manually re-run the nestjs apps. Once i restart the apps only then missed events are replayed, not upon re-connect.

Hi Kodeine,

Thank you for your interest!

The connector is currently been updated these days, and soon a v5 will be release, that will be compatible with the last version of ES, using gRPC, so this shouldn't be an issue anymore after that.

Hello @AlexandreDecollas , I am aware you u guys are working on a newer client version and i'm very excited to start using it. The problem right now is i have a lot of services using the older version of this package and it will take me some time to migrate to the newer version. In the meantime, is it possible to push a hotfix patch for this disconnection issue? I would be really thankful.

i am using "nestjs-geteventstore": "1.6.4",

Update: actually, i just reviewed the latest merge and it seems its easier to update my services to use the newest version and we get the taste of eventstore 20 too.
