Good evening! I am using QGIS 3.44.9 (Soloturn) and Trends.Earth 2.2.10.
First, ensure that you have registered for Trends.Earth (Step1) and Enter Username and Password (step 2).
Second, keep your data somewhere.
Third, press windows botton + R and Run %AppData%, find the folder for your QGIS version, and delete if you wish to install QGIS 3.44.9. Ensure you have stable network connection and install Trends.Earth plugins.
Then search for Trends.Earth API Dashboard and longin using your email and password.
Recommendation
If you have executed many scripts on Trends.Earth, please use new email and password and run require scrpts, then wait for sometime.
I hope this will help out.
Best Regards
Lahai
