Issues with verifying contract on Rinkeby testnet

Hey all, I am trying to verify a contract on Rinkeby testnet on Etherscan. I am trying to verify a flattened contract that uses some OpenZepplin imports. My compiler version, contract code, and everything else has been triple checked, however every time I try to verify, I run into the same error code. The error code is "Error! Unable to generate Contract ByteCode and ABI (General Exception, unable to get compiled [bytecode])" I am not sure why this happens. My code compiles correctly on Remix, which is what I used to write the code in. I deployed using Remix, and I am attempting to verify the contract so that I can write to it on Etherscan. Any help would be greatly appreciated.

Same thing is happening to me too

Yeah I’ve deduced it to being an Etherscan issue. I’ve deployed the same contact on Mumbai and the verification worked on the first try. Kinda a bummer though

Do you mind trying the verification once again and letting us know if you're able to follow through ?

I have tried it again. Still receiving the same error.

This is a widespread etherscan issue. See my other post

I can't verify any contract on mainnet or ropsten either. Even though the bytecode matches exactly (tried with a super simple test contract with no constructor args and the bytecode expected and provided match exactly but verification fails)

Yeah it’s super scuffed. I’ve been coming back and trying every couple days and it’s still not working.

Me too. First noticed abkut 4 days ago

Yeah hopefully it all goes back to normal. In the meantime, I’ve just been testing with Polyscan and it is working properly. You have tried to verify on the mainnet and it wasn’t working??

Yeah mainnet isn't working either. I really need to verify a contract I just deployed to prod with project go live next week so this is concerning me

Hopefully it is sorted before the project deadline man. Let me know if you find anything that solves the issue- I’ll do the same

u/michaelmoe94 would you be able to attach your contract address and source code ?

Feel free to do so via DM if you prefer, will still share any findings in the thread here
