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

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.

Hi @munk,

Totally appreciate it's for illustrative purposes, but I had to remove one of the sites you linked from the post, as it relates to purchasing age restricted items. Thanks for the insight, that some of the instances of SSL error are adult filter related though.

Thanks,
Jonathan

I am using a 3 business data sim in an iPhone and have been getting the same SSL errors at times

It's certainly getting a little long in the tooth, any website or service using SSL (possibly limited to port 443) has problems. I'm probably just going to upgrade my home router to something cable of a VPN at 500+mb so everything in the home just works.

Just checking in once again to see if there have been any changes for any of yourselves

I have been away so I have not been able to do my usual checks

Same as always. 😞  Not much more to add really.

Same issue here - in fact have found a the work remote access site seem to be having issues even when I'm on my VPN which is frustrating!  I see there's been some media coverage on this issue too that may be of interest to folks - https://www.ispreview.co.uk/index.php/2024/09/three-uks-home-broadband-users-suffer-intermittent-con....

Really need to have this situation resolved, would be great to get a progress report on likely timescales @JonathanB ?

For the forum page thats had significantly more posts than any others in its section you'd think there'd be at least some sort of regular updates on what they are doing or at least trying.  Instead it feels like there is maybe a token suggestion at best every couple of months and then silence, making people wonder if they are actively even attempting anything at all or just like "meh....not my job...pass it to the other team"

Still seeing the issue, just wanted to include regular websites where the issue is repeatable for me.

Secure Connection Failed
PR_END_OF_FILE_ERROR

  • en.wikipedia.org
  • mynoise.net

Amazingly it is coming up to almost a year since the original post, and still nothing has changed.

Just to provide my data, amongst others (although it is the same as most others, so is unlikely to add anything new).

Unlike most others, I am on the Huawei H122-373 (as an aside, Three tried to push me onto the Zyxel router, I declined as I don't particularly appreciated being pushed a downgrade), so this is not router specific.

These issues have plagued me for probably a year now. They did not occur when I first signed up with Three. I finally had enough and did a search, only to find this mammoth thread. I waded through about 13 of the 42 pages before realising that there was unlikely to be a solution here. Ironically, I cannot load this thread without activating my VPN (just times out otherwise)

I often get issues connecting to sites with Firefox with PR_END_OF_FILE_ERROR. There seems to be no consistency as to which sites this will happen to and when, and I often have to refresh several times to get the page to load.

Github is pretty much unusable (I am a software developer so that is... fun). The most common error is:

error: RPC failed; curl 18 transfer closed with outstanding read data remaining
error: 62601 bytes of body are still expected
fetch-pack: unexpected disconnect while reading sideband packet
fatal: early EOF
fatal: fetch-pack: invalid index-pack output


Downloads will often fail (be it through firefox, or using curl/wget). They need to be 'retried' to complete.

The short snippet posted earlier in this thread outputs exactly as the original user posted:

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

 

Using a VPN solves this issue. That is neither a practical, nor long-term solution.

This is clearly a major issue within Three's infrastructure affecting a lot of users. I find it staggering that a year on, we are no closer to a solution.

I am happy to provide more information directly if it will help expedite a fix. I am not optimistic.

Like you GitHub is my main nemesis, especially ghcr.io. Most other sites I have visited have been fine in Chrome but I know Chrome automatically retries when it encounters the error, so perhaps I've just come to expect it and not noticed the retries
