MinimServer 2 on Synology: Format Error

[LittleScarabee]

Hi simoncn,

I have checked and updated my QoS on my switch : but issue not solved.
On my first NAS (v 6.1.7) :
* I have checked : firewall not activated. I tried to activate the firewall and allow all flow : issue still not solved.
* After launch MinimWatch on my Mac (OS X 10.11.6) and wait many minutes (around 5 or more) : I can manage MinimServer via MinimWatch and I done NOTHING on my network. My NAS is available and work because I have a activated data transfer from my NAS to the cloud to be sure : everything still up ; no standby etc...

On my secondary NAS (v. 6.2.3) :
* I have installed the lastest version of MinimServer 2.x : No Issue it works without any problem
* As soon as I launch MinimWatch, I can managed MinimServer

I have only one subnet on my network, no specific VLAN, ony QoS but with no impact. I tried to install a old package : minimserver-update-156 ; but it's not possible to install with 2.0.12 (for me it was a stable package with my Synology).

Can you confirm me there is no technical constraint to use MinimServer on Synology 6.1.7 ?

Thanks for your advice
