Version 6.6: sstp Server does not allow bridging

I use Ver 6.5 SSTP tunnels without problems. When I upgrade to Ver 6.6, the SSTP Client side works, but the SSTP Server side reports an error. The error states that the SSTP tunnel cannot be added to the bridge.

When I can use Ver 6.6 on the SSTP Client side with Ver 6.5 on the SSTP Server Side, there are no errors.

The Ver 6.6 release notes do not indicate that there were any changes to SSTP.

Thanks

Issues with BCP and SSTP have been reported in 6.6.

Lets hope for a fix in 6.7

Actually, I tried to recreate the SSTP problem with briding, but for me it works.

Can you provide your exact configs?

This first export command is for a disabled sstp-server:
/interface sstp-server
add disabled=yes name=ppp3 user=ppp3

This export command is for a dynamically established sstp-server:
/interface sstp-server server
set authentication=pap,chap,mschap1 default-profile=sstp_bridging enabled=yes
keepalive-timeout=1 port=44443

The default-profile, sstp_bridging, is:
/ppp profile> print
1 name="sstp_bridging" bridge=bridge1 use-mpls=default
use-compression=default use-vj-compression=default
use-encryption=default only-one=yes change-tcp-mss=default
address-list=""

And bridge1 is:
/interface bridge> print
0 R name="bridge1" mtu=1500 l2mtu=1520 arp=enabled
mac-address=00:0C:42:A5:1C:3A protocol-mode=none priority=0x8000
auto-mac=yes admin-mac=00:00:00:00:00:00 max-message-age=20s
forward-delay=15s transmit-hold-count=6 ageing-time=5m

Bridge1 has static port and a dynamic port for the incoming SSTP connection. This is when it works, otherwise, the dynamic port does not connect:
/interface bridge port> print

INTERFACE BRIDGE PRIORITY PATH-COST HORIZON

0 ether3-master-local bridge1 0x80 10 none
1 D (unknown) bridge1 0x80 10 none

During this SSTP tunnel reconnect attempt, the error occurs. A few seconds later, it connects.

07:30:29 sstp,info ppp3: connecting...

07:30:31 sstp,info ppp3: connected

but a few minutes later, the SSTP tunnel reconnects immediately:
07:37:08 sstp,info ppp3: terminating... - terminated by remote peer
07:37:08 sstp,info ppp3: disconnected
07:37:08 sstp,info ppp3: initializing...
07:37:08 sstp,info ppp3: connecting...
07:37:10 sstp,info ppp3: authenticated
07:37:10 sstp,info ppp3: connected

and again a few minutes later, the SSTP tunnel reconnects immediately:
07:57:01 sstp,info ppp3: terminating... - terminated by remote peer
07:57:01 sstp,info ppp3: disconnected
07:57:01 sstp,info ppp3: initializing...
07:57:01 sstp,info ppp3: connecting...
07:57:03 sstp,info ppp3: authenticated
07:57:03 sstp,info ppp3: connected


The error occurs frequently, but not consistently. When the static SSTP-server binding is enabled, the error is constant. When I use only the dynamically connected SSTP-server binding, the error is less frequent.

Just downloaded v6.7. Tried the BCP over SSTP. Same problem that occurs in v6.6

FYI, I tested BCP over SSTP using v6.5 and no problem.

Problem is present in 6.6 and 6.7.
