Problem connecting to Mychart

[#1]

@Townman 

I can confirm I can connect to the service via a web browser and telnet on port 443 (https) using my Vodafone connection,

If I recall correctly you have Zen connection, do you get the same ping and trace router results?

EDIT:

an end point not responding to pings ought not to stop a trace route 'walking' the path

If tracert is using icmp I'm not sure how it will finish walking the path as you put it

Hi Dan,

The business premises has a Zen connection**, whilst home remains with Plusnet. were you think of @jab1 who is indeed with Zen?

**Remote prodding of the router does not expose any router functionality to ping from the router, so I cannot test connection from that provider.

A restart of a person's home router to get a new IP address and thus re-establish connectivity indicates (to me) a firewall (for some reason) is blocking the end-to-end traffic. A traceroute using TCP packets would be required to get further (IMO).

A refresh of IP Address to a different network range would suggest a routing issue, which firewall are you referring to? can't be the plusnet supplied Hub that is not configurable, for the Hub Two it can either be On / Off / Block all (only allowing inbound port forward traffic.) 

It would be interesting to see if trace route to 157.203.6.154 using TCP works, if I have time I might give it a go using my vodafone hotspot and a Mint 21 desktop as Linux traceroute offers TCP and UDP options

I also had problems with MYchart log-in and contacted Kings College Hospital London who suggested it was my ISP when I told them it was PN. I dropped Wi-Fi on mobile and went on 4G and was able to log-in with no problem. I then tried my neighbours ISP, not PN, and again able to log-in. Called PN to be told "Factory reset router may help"  Do I really want to factory reset and all that would entail? Stick to 4G in future and forget about even trying to use PC as that has never connected to NHS Mychart.

Thanks to everyone who's contributed advice. I've solved my problem by leaving Plusnet (it wasn't the main reason for changing ISP) but I can log in to MyChart with my new provider (Community Fibre).
