Hello,

I can no longer reach duckduckgo and yahoo an probably some others.
I noticed this because i use duckduckgo as search engine.

I try the following cmd

curl -v https://www.yahoo.com

* Trying 87.248.100.215:443...
* Connected to www.yahoo.com (87.248.100.215) port 443 (#0)
* ALPN: offers h2,http/1.1
* TLSv1.3 (OUT), TLS handshake, Client hello (1):
* CAfile: none
* CApath: /etc/ssl/certs

Here it stalls then after a minute or so i get the following back

* Recv failure: Connection reset by peer
* OpenSSL SSL_connect: Connection reset by peer in connection to www.yahoo.com:443
* Closing connection 0
curl: (35) Recv failure: Connection reset by peer

What could be the problem, i have no idea.
System is up to date.

No problems connecting to those sites here. Have you tried a traceroute? See man traceroute for more.

Ok did a traceroute

traceroute to www.yahoo.com takes 12 hops

traceroute to www.duckduckgo.com no response takes 30 hops, use -m 60 no respone after 60 hops
When i use -I it takes 16 hops and when i use -T it takes 22 hops.

This doesn't tell me much i am not a network operator.

Any ideas?

Well, the traceroute seems to indicate that the seek is not being actively blocked, even though it's not getting to its destination. Frankly, I have no idea what the problem may be either, but I have a couple of thoughts for further troubleshooting.

Do you have access to a second computer you can test with? Do you have any friends or acquaintances who are having trouble connecting to those sites?

If you have a location, say a coffee shop or library, that you can take your computer to (assuming it's a laptop), you might try testing from there to see if that makes a difference.

If you are using Firefox, you might try another browser, such as Seamonkey, Konqueror, or Lynx (I think Slackware includes all of those by default), just to rule out that it's some kind of weird browser issue (I'm using Firefox as I type this).

If you have an Android or iPhone, can you connect to the sites with it?

I've had a lot of trouble with Yahoo recently. Sometimes logins go haywire and quite often I get a popup which says "No internet" although I have normal access to other sites. Some problems with their servers?

Just a thought.

As suggested in post #4, above, have you tried another browser? Perhaps, a chrome clone, such as Vivaldi.
It just might be my imagination , but more and more sites seem to be written to perform best with Chrome.
I have trouble with Firefox on a couple of different sites, but both sites work perfectly with Vivaldi (which is not my first choice in browsers as it reports itself as Chrome and I'm not a fan of anything from google).
Anyway, just a thought.

I've had cert problems before when my clock got badly out of sync; is your date/time correct?

uck uck go has so many variations because F/D/C and U/I are so close on the keyboard, but it's always a typo and never intentional, right?

ok i did try different browsers but only tor-browser seems to work to yahoo and duckduckgo all the others fail.

any thoughts on that.

For what it's worth, I'm still experiencing no issues with either site.

So you can reach it with someone else's IP but not yours? Did you get blocked/banned? Did you have a script that was misbehaving? Sometimes startpage blocks me when I get the wrong Tor exit node.

For what it's worth, I'm not having issues accessing either site

Ok it was the MTU size on my ppp interface
