I am having a slight issue here where I have 3 Offline POS systems connected to the same site and on the same network making transactions. 2 of the systems currently have their invoice syncing with no issues. however, one of the systems keeps throwing a request timed out. I thought it was a network issue but after restarting, I can log into frappe/erpnext but whenever i try to sync offline invoices…the same issue still pops up.
Can anyone please assist on this issue?
