ProviderError: HttpProviderError

[Sagezez]

I'm trying to deploy a contract to Mumbai. This has been happening for nearly a week now and I have not been able to deploy. I have searched the error and it has been suggested to set the gas manually as opposed to automatically. Unfortunately, I am unsure where to add in the info.

Hey Dude, exact same Problem here with my project. Since i don´t find any solution, i was wondering if you find a way to fix?

Looks like it is basicly the same problem. Would be very very happy.

I'm sorry for the late reply, I never experienced anything like this before and I couldn't replicate this until the last couple of days when working on Mumbai (Polygon's testnet).
In my case I had to change the RPC endpoint as it was not working properly (you can change it from MetaMask if you are using Truffle). I used a private endpoint from Alchemy and it worked fine.

I hope this helps.

i had the same issue and tried out a few RPCs from chainlist (which i added to mm goerli rpc settings) to get it working
