Some Websites won't load

Hi there, this was going on for ages, but it was usualy websites I didn’t realy care about like t.me (web.telegram.org, telegram.org), pan.baidu.com, etc

but today this domain: https://aadcdn.msauth.net also got affected which is used for login.microsoftonline.com, meaning I cannot login to any microsoft account because its trying to acses stuff from aadcdn.msauth.net and failing

if I do a tracert to this domains

u can see that somewhere along the patch routes just not connect

here is my config

I am not sure what to do now, I already tried

/ip firewall mangle
add action=change-mss chain=forward new-mss=clamp-to-pmtu passthrough=yes \
    protocol=tcp tcp-flags=syn
/ipv6 firewall mangle
add action=change-mss chain=forward new-mss=clamp-to-pmtu passthrough=yes \
    protocol=tcp tcp-flags=syn

But its not helping, this was going on for years, but microsoft account failing (at university we use Microsoft SSO (Single site login) to much, meaning I cannot even login to uni account
Thanks for Anwsering and Best Regerds

I assume you have MTU 1480 for PPPoE. Please try going to IPv6 → ND → double click on “all” and type 1480 in the MTU. Save it.

Hey, it looks like your router is running a nearly 8 years old version of RouterOS, while you are trying to access IPv6 resources. I would say that 8 years ago MikroTik’s support for IPv6 was much less mature than now, and a lot have been fixed/implemented in the meantime. Maybe you should try an upgrade to 6.49.18 first?

Wow, I can’t believe this worked (souch a simple change), can u explain why it works?

I don’t want to upgrade, because later versons removed Master and Slave on the swich chip, as well as the ability to limit the speed direcly on ethernet port

as well as visual changes I don’t like (they removed my favourite icons in winbox), I hate this new icons (and yes, I am running a later ROS version on some of my routers)

If I can upgrade without having this changes I hate, please tell me how (and of course would love to have security issues fixed, but not if I will loose features I like cuz of that)
