Ok this is getting annoying. I cannot invite my friends

More and more I cannot invite my friends. I cannot invite my brother AND my friend. What's happening?

Connection issues?

Try seeing if the ports Warframe use are open in your router.

Can you please make clear what happen when you try do invite?

Sounds like a network issue.  Are you guys all playing on the same network?

Solution: Access Navigation and check if you've set it on Solo or not, THEN invite. If unsuccessful, ask all of them to also access Navigation.

I've been having the same issue for over a year now. It goes like this: you invite people normally, but after a couple of missions/conclave matches, you can't invite. Invitation can't reach other players and you cannot be invited because you appear to be offline. It's not much issue if you play on Public, but invite only games become near impossible, Trade can only be done at Maroo's Bazar for this too.

At least I'm a solo player and not very much affected by this.

With the network issue no, I have a good network.

if the problem is that you cant see the invite option when clicking their name, just press invite squad member, write their name

I did that a thousand times. It either says the host is not here, or he is offline which is not true.
