Many L2TP/IPsec VPN failing since power outage

Wed Jan 12, 2022 9:18 pm

Hello team!!!
Happy new year for all of you!

Yesterday, in several cities in Argentina (My Country) there were a power outage. Since then I have the following issue
I have several VPN clients configured in my PC, one or two for each customer, now, when I try to connect to some VPNs (Not all), I get the following:
16:00:34 ipsec,info respond new phase 1 (Identity Protection): PublicIP1[500]<=>PublicIP2[500] 
16:01:34 ipsec,error phase1 negotiation failed due to time up PublicIP1[500]<=>PublicIP2[500] 989492e694cbf2f7:076c7c0ac2ac92da
However, other users can connect to the same VPN which is failing in my machine, also I can connect to other L2TP/IPsec VPNs and there are many with the same error from my PC.
Also, I have a VPN SSTP to the same router and it is working.
Here the settings in this one mikrotik:
/ip pool
add name=dhcp_l2tp ranges=172.16.0.100-172.16.0.150
/ppp profile
add dns-server=8.8.8.8,8.8.4.4 local-address=172.16.0.1 name=L2TP remote-address=dhcp_l2tp
add dns-server=8.8.8.8,8.8.4.4 local-address=172.16.1.1 name=SSTP remote-address=dhcp_sstp use-encryption=required
/ppp secret
add name=user password=test profile=L2TP service=l2tp
/interface l2tp-server server
set authentication=mschap2 default-profile=L2TP enabled=yes ipsec-secret=Password2 keepalive-timeout=60 max-mru=1460 max-mtu=1460 use-ipsec=required
No IPsec setting was made, it is like default ("/ip ipsec export" shows nothing)

Any idea?
Thanks in advance.
Regards,
Damián

Please search before post. A recent Windows Update broke the built-in VPN client.

Before blaming Transener, check whether the actual reason is not this that incidentally happened at about the same time.

Sorry, you are right
I searched in google, not here and I did not found this
By uninstalling this update KB5009543 in Windows 10, started to work again.

Thanks

Damián
