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.

I'm wondering if content filtering is the issue here.

Ever since turning it on and waiting a few days, then disabling it, I have experienced an increased number of issues.

These issues Re, I think, the filter trying to block or redirect the navigation to the filter notice page.

Rebooting the router gets me a new IP which may or may not be up to date with what the filtering setting is configured to. For example yesterday I was able to access archive.org and a random adult site, the same test today without rebooting the router but I do have a new IP, I am unable to access those same sites.

I double checked the settings and they are still disabled on my account.

This doesn't explain why banking and shopping sites display the same issue, so perhaps I'm wrong.

There is definitely filtering going on but it is deeper than what we can access as customers which is why VPNs and WARP are working

From re-reading the posts in this thread, it seems that the adult content filter makes an already existing problem worse

Router: NR5103E V1.00(ACBJ.0)b15

I've been having the same issue with random web page dropouts or slowdowns to do with SSL (primarily "PR_END_OF_FILE_ERROR" when loading up sites that rely heavily on SSL like Morrisons) since I started the service back last year.  Definitely the Three mobile service / router being the issue - I had a fixed line running at the same time as I started with Three and if I used that connection there were no issues at all.

I think I changed to IPv4 only some time back and that seemed to resolve the issues to some extent, but recently they seem to have changed things on the backend which meant I had to re-enable IPv6 to be able to use the internet at all, and ever since then the page stalls and SSL errors have been coming thick and fast in every single web browsing session (this is on Firefox where I think the issue is exacerbated because of the way it doesn't time out as quickly as on other browsers when this glitch is encountered, where other browsers just continue to load the page without issuing an error).

One site that consistently causes issues is Channel 5 / My5 - trying to view the live channel I always have to hit refresh up to a dozen times before the page loads properly.

I've not complained about it because frankly the level of interest in fixing anything seems quite shocking here and I've resolved myself to the fact that 'you get what you pay for'.  It's not been bad enough to be a major issue that would cause me to really want to complain with a view to leaving - still it seems remarkable that a fundamental issue like this experienced by a large number of people isn't fixed after so long.

Hoped this thread going quieter might have given support the opportunity to address it but nope absolute zilch.....pathetic.  They just hoping the problem going to go away on its own? 

This is now the most commented thread in this broadband section yet its tumbleweed from them in trying to resolve it

Unfortunately I also have nothing new to add - I have given my quick fix solution which is probably the single greatest thing that I could do for anyone that reads this long thread and tries it (Assuming that it works for them)

For now, I am watching the thread hoping that a proper fix comes from Three or an alternative that is better than using WARP

[bytespider]

For me, I've got nothing new to add, but it's still the same. I'm checking out the aforementioned IDnet, but the 12 month contract is putting me off. I might try Honest mobile. Unfortunately other carriers signal is terrible for me as I'm on the outskirts of the city.

FWIW I switched to IDNet's 5g service, which also runs ontop of Three's infrastructure so I can point my antenna at the exact same mast. I no longer have any of these issues with dropped packets.

It's a bit more expensive and I've noticed around an extra 10-15ms latencey on average, but most importantly it actually works.

Given that IDNet uses Three's 5G network, do they use the same APN details? I would often switch between using Three's stated APNs of 3internet (Most problematic) and three.co.uk (Currently using) whenever I had issues but using WARP has stopped me from doing so

[Midnight54]

sigh - noticed now today that Three have enabled adult content filter.

I can't log in using my Three broadband sim number because it wants me to "register again" since they made their changes, but my other phone sim is registered with the address etc and so it just fails and round in circles.

So more faff to have to contact them to sort that account to a) disable adult blocking, b)moan about this issue to them and find when my contract comes to end

ok so rebooting my router this morning, and content filter is off - so no clue what that was about - I'd been rebooting it a few times earlier that day whilst adding an OpenWRT router into the mix
