Sophos Firewall: v19.5 MR3: Feedback and experiences

I'm seeing SSL-VPN Connections not being accepted after Upgrade from MR2 in my demo-lab (sfos-home).
SSL-VPN is enabled on WAN-Zone but no connection successful. Device Access ACL seems to block but i can't tell why as settings are fine.

drppkt on advanced shell showing "log_type=Firewall log_component=Local_ACLs log_subtype=Denied"

ACL is fine:

Did this configuration work in V19.5 MR2? 

Do you have a WAF configured? 

yes, I'm quite sure - and no waf-rules, no dnat active.
You're asking because of 443 udp?

Check the sslvpn.log on CLI for more insights. 

No connections at all - i think traffic is not getting forewarded to ssl-vpn, as visible in drppkt?

I have DM you for support access.

It’s not related to MR3 or upgrade, we have captured the logs for further investigation.

It looks like while SSLVPN service was coming up it got timed out and terminated by the parent service, but it returned error for termination request and hence it got stuck. Historically, we have seen a similar issue once earlier on another version by one of the customers. 

Appliance reboot has resolved the problem for now.

Yes, thank you very much Alok !
