They have not found a block in a while is the reason for the delay.

Looks like it has been 2 days since last found block.

i had an issue with LN payouts thru Ocean for some time in the past; all of them went thru eventually; however, i gave up and solo-mined ever since; honestly, if the economics of pooled-mining payouts are not very important to u, go with Braiins pool for consistency and regular payouts; u will be able to confidently demonstrate to people the entire process with a few clicks on ur mobile screen;
