Hi, I had the same, I was using WSL and I'd solved it by:

1. Open Ganache > Settings > Server > Change a) Hostname: choose the one with WSL in brackets; b) Network id: set 1337 > Save changes > Restart Ganache
2. Rewrite your code to accommodate for changes in 1) > choose an address in Ganache > insert your public&private keys in your code

Hope it will work for you

oh yeah it works thanks a lot ! @hre4anyk @cromewar

Also @cromewar just a suggestion, maybe u can create a discord group based on this specific course so the newbies (like me) can get help faster by more people

[cromewar]

There is a discord server from chain link on which you can get a lot of support from a lot of developers, but still is a good a idea, what do you think @PatrickAlphaC ?

[freddie71010]

I would gladly be part of that discord to help people out too!

[PatrickAlphaC]

That might be good!

I actually like forums more because questions and answers are searchable. The Chainlink discord is a great place though and you'll meet a ton of developers who have gone through this course :)
