Lori-77 I have entered the standard DNS servers from Swisscom, as before… with swisscom on the hotline it also worked with 4 different employees… the LED was constantly lit white the cable is not kinked…
r00t I have sent you the address privately.
Thanks for the hostname, I can easily reach it from my connection and also resolve it correctly.
Do you see e.g. with tcpdump the traffic arriving at your server? If not, I would get @ChristianEb on board to see if there is a problem somewhere in the network.

Is it possibly the same problem as in this post https://community.swisscom.ch/d/804448-schrankt-die-swisscom-das-aufrufen-von-internetseiten-ein @ChristianEb?

WalterB yes already several times, even with a new swisscom büx it doesn’t work….. is really tedious… maybe it’s because I’m an init7 customer and therefore a thorn in Swisscom’s side…
This has nothing to do with you being with a different ISP.
As long as the website is not on a blacklist, it must be accessible.
What happens if you open a VPN on a test basis with a Swisscom connection, can the server then be reached? Because you are tunnelling through the Swisscom infrastructure.

There are three possible causes: either the DNS or the routing or a protection mechanism of the target system. Your comment that it worked briefly after the technician’s visit could be explained by the fact that your router was given a new IP at the time, but this was then quickly blocked. At least the first two causes can be narrowed down with the simple on-board tools of the operating system, as r00t already wrote above.
@Diochengion11 If you compare the output of the command “nslookup mail.meindomain.xx” with that of “nslookup mail.meindomain.xx 8.8.8.8” in a command line window, do you notice a difference? What output does the command give if you run it from an Init7 or Thurcom connection? If the results were only different on the Swisscom connection or with the Swisscom DNS, you would have to look further for the error in the DNS. An online DNS resolver, which can also detect any subtle DNS misconfigurations, may help. For example this one: https://www.diggui.com/
If the DNS is good, check the routing next. Can you ping your mail server (command line “ping mail.mydomain.xx”)? If not, how far does a traceroute get (command line “tracert mail.mydomain.xx”, a few unreachable lines are normal)?
Basically, does mail.meindomain.xx only have an IPv4 address or also an IPv6 address? And how exactly do you access the mail server, i.e. with which protocols? IMAP/POP/SMTP? Encrypted? I don’t assume and hope you don’t, but TCP port 25 is blocked outgoing at Swisscom, and for good reason.
Have you tried turning it off and on again?
Diochengion11 Hello, unfortunately there is still a problem with the mailavisation in the Swisscomcommunity, which is why the mention did not work here, but thanks to @r00t for triggering via other ways…
I had a quick look at this and I see that in my home region the call seems to work.
may i ask if you could share two traceroutes via direct message from source to destination and from dest to src from the case where it doesn’t work?
as there are only two ASN (AS13030, AS3303) in the path I don’t see any relevance to the case mentioned here….
greetings and thanks

Swisscom Network Engineer IP+ AS3303,
how do you come up with something like that?
The point of the internet is to connect IPs.
No matter what you think of a person (e.g. Fredy as CEO of AS13030), it’s all about the Internet and nothing else…
Here in the community we don’t have to politicise either, I think we’d better try to do some sensible troubleshooting here….
Swisscom Network Engineer IP+ AS3303,
ChristianEb I sent you everything last night.
Diochengion11 basically this forum works, yes….
but it is advisable to know that you are not opening a ticket here, but that you can expect answers in a user community that looks at what it can do on a goodwill basis….
Swisscom Network Engineer IP+ AS3303,
Diochengion11 already works, sometimes it just has dropouts (timeouts).
If you are waiting for an answer to your problem, then you need to be patient,
This is not the official support channel of Swisscom.
The Swisscom employees who stop by here and provide additional help do so voluntarily and in their free time.
Diochengion11 It would work better if you also answered the questions questions. A decent tone of voice also increases the chances of getting useful answers.
Have you tried turning it off and on again?
PowerMac i have replied to people privately. i don’t have a gmx address that is accessible to everyone…. but i have noticed that no mail notifications are coming… that’s why i ask if the forum works at all.
The community is already working but has intermittent failures because it is still rebuilding, it has even been found that it is mostly at 1-5 minutes time setting, e.g. 10:01 - 10:05 or 14:01 - 14:05, could also determine it.
Installationen, Netzwerk, Internet, Computertechnik, OS Windows, Apple und Linux.
The notifications work perfectly for me.
Maybe something is wrong in your notification settings:
https://community.swisscom.ch/settings
Green tick on
Red cross off
And of course the e-mail address to which the community notifications are to be sent must also be entered correctly in MySwisscom:

Stephan_76 thanks, I tried that over and over again and always got a red error message…. but now it finally worked…
