Domoticz error sending data to Influxdb

[NvBgm55]

Recently I replaced my old raspberry with a raspberry pi4. I only run Domoticz on this. On another raspberry pi3b+ I have Influxdb and Grafana running. I have Domoticz send data to Influxdb. Previously this went without any problems. Even now it seems to be going fine. However, every now and then I get an error in the log file.

2021-12-15 20:16:07.675 Error: InfluxLink: Error sending data to InfluxDB server! (check address/port/database/username/password)

Does anyone have an explanation for this??
address/port/database/username/password are okay. after all, the rest all go to the database. :

I find out it is de new PI4 thats freezing now and then .

Did you manage to solve your problem? I am experiencing the same problems.

Seems that Infuxdb or system is blocking communication for some reason.
If it is every now and than I would check for a network hickup (if on different systems), backup, CPU overload etc on the time of the error.
Are they coming back on a regular schedule (every x hours/minutes)?

Same here:

Code: Select all

Error: InfluxLink: Error sending data to InfluxDB server! (check address/port/database/username/password)

I deleted all things possibly connecte with influx or grafana.

Code: Select all

:~ $ sudo find / -name '*nflu*' -delete
~ $ sudo find / -name '*rafan*' -delete

Situation persists.

It seems to be related to influxDB so check the log file of influxDB for clues. Also check influxDB community for connection refused errors.

There's nothing influx installed on my RPI.
All instances influxdb are deleted and still Domoticz is logging the forementioned line.

Domoticz tries to try send some data to influxdb.
Maybe I have installed something in Domoticz which I removed later on and Domoticz persists in trying to send data.

Did you look in menu Setup - More options - Data Push - InfluxDB
