Dongle flashing red and won't connect to Wifi

Hi All
I am having difficulty connecting to the FOXESS app. The solar system itself is working perfectly, but I am unable to complete the WLAN CONFIGURATION. I've tried doing the manual input but whenever attempting to connect to the dongle wifi "W-xxxxxx" I get a message that states incorrect password. I am using the default "mtmt2020" password, but it still states incorrect password.

I did reset my router previously and if I recall correctly this issue started thereafter. Not sure if this has any relevance or if there is a troubleshoot...

The dongle itself is constantly flashing red rapidly, but as aforementioned when trying to put in the password for the WLAN CONFIGURATION I get an incorrect password prompt.

Something to note. The "Site" was previously set up and as such I do have that present on the FOXESS app, but as I cannot connect the dongle the data is not populated.

thanks in advance

Assuming you haven't changed the password, if it is a newer datalogger try using the app to connect to it as per the video in this post
