Thingworx Influx Not estabilishing the connectivity

We have a Thingworx 9.5 and Influx 1.7.9.

It was working fine for a very long time. Recently, the connection is not working as expected. We are getting following message from Influx log.

tcp.Mux: handler not registered: 71. Connection from 127.0.0.1:52517 closed

 In Thingworx,

[O: c.t.p.i.InfluxdbDatasource] [I: ] [U: Administrator] [S: ] [P: ] [T: http-nio-8080-exec-9] Data Source thingworx connectivity test failed! with [2,002] No connection. Contact the administrator.

  can you someone help us?

Influx is running with following cmd:

influxd.exe -config "C:\influxdb.config"
