Hi there,

I’ve been using UQLab for a while and it has been working great. I just encountered a connection error for the first time. Please see attached screenshots for the detailed error messages.

I’ve run similar analyses before so I don’t quite understand why this error suddenly happended. I actually just resumed my analysis and now UQLab is working again.

By any chance, does anyone know why this would happen and if there is anything I should/could do to avoid this in the future? This is important because I will move my analyses to clusters and this unexpected error could disrupt scheduling.

Thank you for your help in advance!

Sincerely,  
Xinyue
