Hello, I got ‘connection refused’ response, then I tried several troubleshoot but doesn’t seem helpful so far. Tried with --debug-challenges, the challenge URL is accessible from browser, had no idea why the server cannot access it https://letsdebug.net/jakartatimur.imigrasi.go.id/79943 said Ge…

[image] rasm: My web server is (include version): Apache/2.4.29 (Ubuntu) The "connection refused" error indicates that your server is not actually listening with Apache on port 80 at the moment. And indeed, that seems to be the case: $ curl -X GET -I jakartatimur.imigrasi.go.id curl: (7) Fai…

Thanks for the response @_az [image] _az: $ curl -X GET -I jakartatimur.imigrasi.go.id curl: (7) Failed to connect to jakartatimur.imigrasi.go.id port 80: Connection refused Where is your location from? It worked fine from JKT curl -X GET -I jakartatimur.imigrasi.go.id HTTP/1.1 200 OK Date:…

[image] rasm: Where is your location from? It worked fine from JKT I am trying from a couple of different locations - both behave the same way. After your change, there is a curious symptom. The first curl request fails with "connection refused". Subsequent requests then succeed. But if I …

Here is a way to reproduce the problem from an external perspective: If we sleep for 10 seconds between requests in a loop, they (almost) all fail: # for i in `seq 1 5`; do curl -I http://180.178.97.84; sleep 10; done curl: (7) Failed to connect to 180.178.97.84 port 80: Connection refused curl: (…

That’s quite strange. I even tried with 20s sleep, all succeeded. FYI, my internet is using different ISP then my server use. And as you can see the URL-checks here https://check-your-website.server-daten.de/?q=jakartatimur.imigrasi.go.id , doesn’t seem a problem.

Since https://letsdebug.net/jakartatimur.imigrasi.go.id/79956 can reproduce the problem, you might have luck re-running the test a few times via Let’s Debug while running a packet capture from your server, e.g. sudo tcpdump -i "eth0" "host 172.104.24.29" You might be able to catch what’s happening…

Hi @rasm [image] rasm: And as you can see the URL-checks here https://check-your-website.server-daten.de/?q=jakartatimur.imigrasi.go.id , doesn’t seem a problem. "check your website" -> server are in Berlin, Germany. But if letsdebug doesn't work, you must have regional settings (firewall or…

I believe the captured packet during letsdebug test is the following 17:10:59.741692 IP (tos 0x0, ttl 52, id 43904, offset 0, flags [DF], proto TCP (6), length 160) 180.178.97.82.52166 > 172.100.1.2.80: Flags [P.], cksum 0xabdc (correct), seq 1:109, ack 1, win 229, options [nop,nop,TS val 19643…

[image] JuergenAuer: But if letsdebug doesn’t work, you must have regional settings (firewall or something else), that blocks. Since my server is behind NAT, any other checks to pass?

[image] rasm: any other checks to pass? I have no idea. You can connect Letsencrypt and you are able to start a new order. But Letsencrypt can't connect your server. May be the Letsencrypt log has more informations. You can - one time - use dns validation and --manual, that should always wo…
