BIP 32 child key derivation "stops working" after a certain index (i)
Mycelium HD is BIP 44 compliant. As specified by BIP 44, the address gap limit is 20. This means that after 20 indexes of unused addresses, the wallet expects that no more addresses are used beyond ...

Is there any service/api for deriving HD wallet addresses from a master public key?
I ended up writing my own command-line tool to perform wallet discovery and print out a report.
It supports single xpub derivation as well as multisig m-of-n wallets, specifically CoPay wallets.

Whether I have to scan all types of addresses to discover BIP44 wallet from mnemonic?
That depends on what kind of wallet you have.
The derivation path is designed to tell you which types of addresses you need to.
