HTTP ERROR 500 when trying to access to the HUB

[OmarBenSalem]

Hi guys ( mto‌ )

Today, when I try to access to the HUB, It won't open (returns error 500).

For ur information:

- I can ping the server ; thus it's not down

- Friday, all was working and I do not have any reloading task. I reload all the application manually for now

=> I really don't have any idea on what could cause this?

Any hint/help please?
