[indexample]

having the same issue,

technically, the error message seems like an issue with async in NodeJS

i have a similar issue running here, maybe i chose the wrong repo (zigbee2mqtt vs hassio-zigbee2mqtt):

[Koenkk]

The real error is [2024-10-09 16:40:02] info: zh:zstack:znp: Socket error, meaning it cannot connect to the dongle, I've extended the error logging a bit, can you see what is logged now?

Changes will be available in the dev branch in a few hours from now.

[indexample]

i have tried with the dev branch / edge
it runs for about 5 and a half minutes, then: Socket error Error: read ECONNRESET

That indicates your network connection is not stable

[indexample]

Any test you recommend that would convince you the network is stable?

Im running quite a large setup and this is the only one with issues

[Koenkk]

It could also be an issue of the coordinator itself, in the past I read people having these issues when opening the web page of the coordinator.

[indexample]

i think i worked it out, and if so, it was a network issue indeed.

after diving into it more, there was a warning in my unify switch portal:
Multiple devices are using the same IP address: 192.168.2.X. Please check each device's configuration to ensure none are communicating with a rogue DHCP server.

the coordinator had hardcoded ip/dhcp settings, and the same static lease from router, but with different MAC address. For some reason the coordinator had gotten a different mac address over time (should these not be stable per device?!), which i believe would be the cause for this issue (in combination with the settings).

now, after changing the coordinator to dhcp settings, the addon has been running well for over 1hr.

This issue is stale because it has been open 30 days with no activity. Remove stale label or comment or this will be closed in 7 days

I suddenly ran into the same issue today. For me it definitely wasn't network related. Restarting the device did not fix the issue. What did solve it was setting the device to usb mode and back to network. Afterwards z2m was able to connect again. So it's definitely an issue with the slzb6 firmware getting stuck.

[andlinux007]

I reverted back to V2.6.8.dev26 in the slzb6.
Since I had done an update of the slzb6 firmware nothing worked in my Home Assistant.

Today after the update errors appeared:

No changes helped, only this advice helped, I sincerely thank the author.

For what it's worth, I ran into this issue after updating to firmware 2.7.0.
The fix for me after much time digging was to change the ip address of the SLZB. Increased it by one, edited it in Z2M and all is well.

[tempomode]

Same issue here with SLZB-06 on 2.7.0 - switching to USB mode and back didn't work for me (if you do this and don't have easy access to use USB with your SLZB, make sure you enable "Keep ON Wi-Fi/Ethernet network & web server in USB mode"!) but removing the static address I had configured in my router and setting a new one solved the problem. Thanks @subseatech and others here!
