Intermittent connection issues loading/changing site- secure connection failed/site can't be reached

[EDIflyer]

Is anyone else occasionally getting a 'connection down' error from Chrome (or 'Secure Connection Failed' from Firefox) when changing page - if I hit refresh it works fine. At first I wondered if it was the site I was using but have noticed it on multiple different major websites over the past couple of months and not noticed it from other locations where I don't use Three Broadband so does seem to be related to the router/connection (this is via wired Ethernet too, so not a WiFi problem).  I've tried changing DNS server in case that helps but no difference.

It mainly seems to happen when trying to first load a site or (annoyingly) at checkout when a different site is being loaded as part of the checkout process.  It certainly doesn't happen everytime but does happen with reasonable frequency.  I've also noticed I often get it when trying to pull/push from/to Github too and have to do so a number of times for it to work (browsing the Github website works fine).

I'm using a NR5103E with Firmware Version V1.00(ACBJ.0)b14 - I tried rebooting it but to no effect.

Just to update - still seeing it occasionally, albeit much less than before...

for i in {1..100}; do curl -I --no-progress-meter -o /dev/null https://github.com || true; done;
curl: (35) OpenSSL SSL_connect: Connection reset by peer in connection to github.com:443

@JonathanB although improved definitely still not fixed - still seeing intermittent issues when I'm not on VPN.

I can't see my earlier reply on this topic, but I also had the same issues updating Home Assistant this evening whilst connected to Three Broadband using my FWA710 not NR5103e. I tried repeatedly before swapping to my BT FTTC service where it worked first attempt.

I am not seeing intermittent page loading issues on this new router, but the problem getting content from GitHub was exactly the same for me tonight.

Hey @BrummyGit,

Sorry about that, our automated Spam filter must have not liked something about the post. I think it may have seen the text and URLs in the log extract as a bit suspicious. I've restored the post now though.

Thanks,
JonathanB

Thank you @JonathanB - this is interesting that I suffered the same issue with GitHub using a FWA710 router therefore it's either a general issue with Zyxel firmware or, most likely, caused by something in Three's infrastructure. I would tend to suspect something like transparent proxy services, content scanning or similar. This might also explain the intermittent nature of the problem as it could be load related.

As an example, we recently had an issue at work where the client's proxy servers were unable to cope with the load and started dropped what it considered to be "long lived" sessions. This meant that some applications that relied on continuous connections failed. It may be that the GitHub Get isn't given long enough to complete before the connection is dropped.

However I still don't understand why GitHub was consistently failing (just like some of my previous examples where it turned out to be the adult content filter) and other pages where it's relatively infrequent. I haven't had any of the infrequent issues since swapping router.

Interestingly I just ran into a problem updating my Home Assistant software. It was consistently failing pulling updates from the GitHub, however swapping to my BT FTTC service saw it update first attempt. Here is an extract from the log:

This has been happening to me intermittently when using github.com over the last couple of weeks / months too.

Not sure exactly how long as I've been running with 2 broadband providers but my other contract just lapsed so I'm now on 3 5G broadband 100% of the time.

It's happening quite a lot and like others on this thread, I'm concerned at how long it's taking to get a resolution.

I've just gone through the process of enabling adult content to see if that helps, but the intermittent SSL issues when accessing github.com are still there.

Is it helpful if I provide any details to your engineering team? Please let me know if it is.

Hey @hughesceri,

I'll PM you a link to the team that @EDIflyer mentioned. If you can chat with the team, they'll gather some info to get your connection info added to the investigation.

It's worth contacting the social media team and including this thread in your message saying you've been asked to get in touch so they can get your account details and send them to the technical team.

After experiencing the PR_END_OF_FILE_ERROR consistently for several months, I have not encountered a single occurrence in the past few days. I will continue to monitor the situation, and it would be helpful to understand if any recent changes have contributed to the resolution of this issue.
