I am following remix connection manual. Running remixd like this:

remixd -s ~/myProjects/cleanKyber/smart-contracts/contractsV5/ --remix-ide https://remix.ethereum.org/

trying to connect and getting this message on terminal:

Connection from origin https://remix.ethereum.org rejected.

Following related questions, I made sure


in both places is used.

Found it, stupid mistake, but I missed it, so for anyone interested.

It was the extra '/' in my URL.

so had to use:

remixd -s ~/myProjects/cleanKyber/smart-contracts/contractsV5/ --remix-ide https://remix.ethereum.org

and not:

remixd -s ~/myProjects/cleanKyber/smart-contracts/contractsV5/ --remix-ide https://remix.ethereum.org/


I also had this error trying to run it on windows PowerShell and connect from Chrome.

Odd thing is it worked fine in Brave. I was able to connect from Brave to remixd running from PowerShell just fine. However, to get it to connect from chrome on windows, I have to switch from from PowerShell to the old command prompt, and then it works a charm again.


I was figuring out something and reached here. You do not need to give the --remix-ide part at all if you are just running one instance.
