Cannot verify a smart contract on Etherscan

[0xdavinci]

I deployed the smart contract on Sepolia.
My contract used solidity 0.8.28 .
Here is my contract address.
https://sepolia.etherscan.io/address/0x69be1adb241e9215633f48fee8d7532da77c83d0
I tried to verify and publish my contract source code.
I set the Compiler Version to v0.8.28+commit.7893614a.

Error! Unable to generate Contract Bytecode and ABI

Hello @0xdavinci, I always verify my contract the moment I deploy using the foundry --verify flag, as I wasn't successful when I tried to verify an already deployed contract on etherscan UI. I trust someone that know what could be wrong will see this and respond as soon as possible.

how do you add that flag in remix ide?

Hi
I had similar experience. Once i did verify, once i did not
any suggestions?

[EngrPips]

I am not sure what the best suggestion will be but verifying at deployment time have always worked for me.

@0xdavinci @EdwinFairchild @DCVglobalnetwork If you want to verify you contract after has been deployed, you need to use a plugin on Remix called contract verification.

to use it on etherscan you need your etherscan API key otherwise you can use blockscout.
If you're in forge, provided you have your etherscan api key, simply use the --verify flag as @EngrPips suggested or use one of the methods described in the foundry book

Great heads-up.

@KMean KMean yes thank you for your help I also figured out that my compiler version did not match the one I deployed. So always has to match the compiler vision with deployed one.

Interesting.
