I am using the latest version of MCUxpresso, and it is insisting it wants to update the pemicro drivers and SDK handler (see attached picture). On running the update, it dies with the error that it cannot get one of the files, with connection reset error (see attached picture). I have already checked with our IT dept, who say that it isn't blocked, and indeed it can be downloaded by entering the same URL into Chrome. Any ideas how I can persuade the IDE to update itself successfully??
Just to let you know this has finally ben solved.
Even though the IT bods insisted that I should be able to get the file, and even though I could manually download the same file in Chrome, it does indeed look like it is some kind of networking issue.
I took the PC home at the weekend, and tried it on my home network, and MCUxpresso updated perfectly happily.
Yes, I have had a moan at our IT dept, but I suspect I will still have the same issue next time there is an update :smileysad:
This is almost certainly a networking issue that is preventing the IDE from communicating with the update sites, not something wrong in the IDE itself.
One workaround we have seen help here in the past ourselves was to provide an alternate DNS server in your network configuration to look up the site names (as the corporate DNS was refusing to resolve the lookups correctly). So maybe try adding OpenDNS (22.214.171.124) or Google (126.96.36.199) as secondary DNS servers.

What is the OS that you are working on?
If you are working on Windows 10, could you please uninstall and install MCUxpresso? I tested by my side and with other computers and the new driver update works without any problem.
I'm using Windows 10 1903.
I tried your suggestion of uninstalling, and reinstalling, but the result using either upgrade method is still exactly the same.
As it's not a critical update, maybe it's not worth spending much more time chasing the fault, and just wait until a new IDE version is released.
I tried following your method, but unfortunately got exactly the same error as I previously described.
