Connection error all the time after v 5.0.2

Hi here a moderator from the Netherlands,

This is a community forum and your posts, questions and suggestions will not be read by Athom. You can read more about this here Welcome to the forum..

For support or issue resolution, first have a look at support.athom.com. If you are unable to find the answer to your question on support.athom.com you can send a support request to Athom via https://support.athom.com/hc/requests/new.
If you need help you can read more about how to submit a support request.
When filing a support request, make sure you add all necessary information so Athom can help you as quickly as possible.

I have had no connection Issues here with v5.0.2 or even v5.0.4 now, nor hear many on the community or on Slack.
The Experimental versions are extensively pre-tested at Athom, in the AATP Community Test group and probably by a couple of 1000 users running it as Experimental before it is released to stable. If you want to complain about that please contact Athom direct as it is of no use to complain at the Community.

In case you want more help from the community to solve your issue, please read [Tip] Problems with Homey? and report more information and in your case maybe even information about your WiFi Network. (or specify clearly what you experience for connection problems so the community can verify.)
