Problem when hosting with incoming https traffic

[rlyness]

I've hosted a football guessing website for a number of years on a dedicated server in my house (just for my friends for some fun).  I've had no problems until a few weeks ago when I renewed my contract with EE broadband.

Now, I am getting weird intermitting problems with some of the guys trying to connect to my website.  When they're on their home internet (different providers), they get a "Site cannot be reached ERR_TIMED_OUT" error - but when they drop off wifi and go on mobile internet, it magically just works.  To add, sometimes when I restart the router it suddenly works for a while then stops working again.

I've got a dynamic DNS set on my router so I know it's not a problem with routing.  It just, for some reason is not responding while on their home WIFI.  Also, it's not all users - some can access fine both on home WIFI and mobile.  It only seems to be https traffic affected, coming through on http fine all of the time.  My certs are valid, my port forwarding hasn't changed for years so I know all that is setup fine.

I've done a full factory reset of the router, I've temporarily hosted the site on a different machine on the network.  I'm all out of ideas.  Anyone had any similar experience?

Hi @rlyness,

Welcome to the Community!

I'm sorry to hear about the trouble you're having with your website, and I can understand your concern.

Do you know which WiFi provider the users who are struggling to connect to your site are using?

Anything changed at your end other than the act of renewing?

Does your router/network have any intrusion prevention/security software running that might be triggering false positives?

Is your Dynamic DNS just publishing an IPv4 address, or is it doing IPv6 too? Could the intermittency be due to whether or not the connection is attempted over IPv4 or IPv6 I wonder?

Does your router/website have any logging that you could check when these failures are encountered?

Are there any parental controls software/services running on the connections those having problems are using?

I do know that 2 of the guys are on Virgin and another on Fibrus.  I didn't ask some of the others.

Hi @bobpullen 

Thank you for your response.  I can't think of anything that has changed that would cause this kind of problem.

I believe the DynDNS only publishes IPv4 but I would need to check this when I get home.  I don't have any parental controls enabled on the router at all.  I'm not sure where I would look for the logging to see if there are any obvious errors logged.  It's just weird that it worked for so long and suddenly stopped.

What router are you using @rlyness?

Hi @bobpullen 

I have a Smart Hub 6 plus.  I do know there have been some significant software updates recently as I was previously unable to use the DynDNS service on the router but I now do have that option.

I don't think it's related but I do also suffer from this problem outlined on another thread: https://community.ee.co.uk/t5/Broadband-Landline/Microsoft-Teams/td-p/1555576

@rlyness - do you have the EE App setup and if so is 'Advanced Web Protect' enabled? Whilst not a Parental Control setting per se, that is intended to block any inbound traffic it thinks is 'sus'.

Hi @bobpullen 

I checked the app and it seems that feature is currently "activating" and won't seem to allow me to change it. I'm currently out of the house right now so I can check again later.

I have a screenshot but can't see here how to attach
