For what I know, the issue is that you are trying to place a BOLT12 invoice that is generated by a different wallet (coinos in this case). You'll be maybe able to sign the message anyhow, but for OCEAN will be a mismatch because the BOLT12 invoice should be signed with the same wallet that generated the btc1 address used as mining username.
