Describe the bug

I am trying to verify two recently deployed contracts on arbitrum-goerli:

1. https://goerli-rollup-explorer.arbitrum.io/address/0x0a2841630f198745a55C4dab3fE98f77271949E5
2. https://goerli-rollup-explorer.arbitrum.io/address/0x652a2A2876B855d9c30d9265F882F0a486608976

from terminal (I also tried w /api appended to verifier-url w no luck):

$ forge verify-contract 0x0a2841630f198745a55C4dab3fE98f77271949E5 src/VestingModuleFactory.sol:VestingModuleFactory --chain-id 421613 --compiler-version v0.8.13+commit.abaa5c0e --num-of-optimizations 200 --verifier-url https://goerli-rollup.arbitrum.io --verifier blockscout

^C

I also tried manual verification thru the site but wasn’t sure how to manipulate the json in out/ to get it to succeed (it didn’t accept as is – i tried deleting keys it was complaining about going off the solidity docs to match solc input json but wasn’t able to solve it)

note: bug may be due to blockscout service being degraded or something – the explorer has been very funky the past couple of days (e.g. it isn’t even recognizing 0x652a2A2876B855d9c30d9265F882F0a486608976 as a contract)
