This is a copy from https://github.com/blynkkk/blynk-server.
Blynk server repository was offline some time ago. Then the log4j vul was found. After doom369 has fixed the repo, i have cloned it because i have the server running locally for my house, so i have a dependence of it. This clone is in a lower healthy as the original source. So the original source would be the best for you.
I have forked the blynk-blynk server to https://github.com/DANSI/blynk-server, because i realize, that the forked one is not deleted or removed automaticly by github, when the original repo is deleted/removed.
Please remove your dependencies to this repo and change to the original source , or my forked one, if you want.
I plan to remove this repo in the future forked one.
