LTC pool not start due getblocktemplate error

[btclinux]

Unable to update job. Daemon responded with: getblocktemplate must be called with the segwit & mweb rule sets (call with {"rules": ["mweb", "segwit"]}) Code -8

[seperatis]

Haven't seen this one before. Can you share your config?

It works with Litecoin 0.18.1 but not with Litecoin 0.21+ due MWEB implementation

[Spollock2020]

Confirmed that adding "blockTemplateRpcExtraParams": ["mweb"], to the litecoin coins.json section DOES NOT fix the issue.

@btclinux @seperatis did you guys find any turn around for LTC, mweb?

[btclinux]

I tried to add mweb to GetBlockTemplateParams this way btclinux@c38f218, pool is up but reject blocks in testnet
