I have used super glue it's really hit and miss, often it does not work. I use IPA to clean PA, but something with superglue and most epoxies and nylon.....maybe the glue joint is just to rigid for flexible nylon?
Hot glue I have used before and thanks to PK's confirmation I'll have confidence to use it between the connector and the board.
Silicone sealant I haven't used before with nylon....I'll put dabs between the case and connector to make the connector more resistant to bending. If just find one neutral one. I probably have few tubes of polyurethane glues for various purposes, but haven't used silicone for ages.
Thank you
