Hub One firewall errors - invalid packet causing web site lock-up?

[#1]

I am seeing numerous messages in my Hub One router logs regarding TCP errors similar to the example below referring to my M1 iMac:

OUT: BLOCK [65] First packet is Invalid (Invalid tcp flags for current tcp state: TCP [192.168.0.84]:59156- >[194.66.200.25]:443 on ppp3)

The error seems to occur coincidentally with a lockup of the website that I am trying to access. I have to renew the IP lease and to re-authenticate to progress any further. I have swapped browsers from Firefox to Safari but still see the error entry in the hub logs so it’s not a browser issue. I log this error a few times a day for the example above. I also see similar errors on other devices as well, including an Amazon Echo ( strange!) but they do not seem to cause a noticeable problem.

Is this problem resolved by the Hub One software update that is available ( on request it seems)?  Until I split my Wi-Fi channels I was getting a lot of disconnections but I have everything on 2.4 GHz now rather than 5 and disconnections seem to be less frequent.

Hey @StuartJP,

I'm sorry to hear about this. Do you know which version of the firmware your router is running on?

Hi! It’s on Software version 4.7.5.1.83.8.263 | Last updated 18/02/19).
I have requested via this forum and Bob Pullen an update to the latest version but nothing has happened yet.

Thanks for confirming this. I'm afraid I can't say when that thread may be updated, but I'll enquire about this.
