Like many here I do admin for some family and friends. In the past I've used a few apps but Teamviewer (TV) has been the best for my situation, now however I'm finding that it can't be used because it's blocked by my friends browsers!?
Obviously it's difficult because I'm getting this second-hand, checking with Browserling there doesn't appear to be a problem - but the last two times I've tried to get someone to download TV [both are on Win10] then they've said that the browser gives them a message that the site "isn't secure" and so they can't download the client.
One has Ad-Aware anti-virus and that blocked emails that I sent with the TV quickstart app and/or a link to the same. Facebook even refuses to send a message with a link to Teamviewer.com and bit.ly appeared to provide a work around but failed to link my friend to the website (worked for me, not for them, don't know which app is blocking that).
So ... is there anything I can do to set up an ad-hoc support session?
They're not up to doing things like finding an IP address for me, at least not without it being like wading through treacle carrying a two year old, and certainly won't be able to check ports are open and such. I'm on an Ubuntu variant and they are on Windows 10.
When I next have access then I'll patch something together with either tightvnc or Teamviewer, but the whole point is remote support and minimising me driving around the countryside just to find the right box to type a password in or whatever needs doing this time.
