Can your server reach IPS servers?  
Try something like 
wget https://remoteservices.invisionpower.com
Do you have some sort of local firewall filtering outbound web requests?  

If you have root level access, you might be able to check through the following command:
curl --help all | grep -- --tlsv You should get some output that looks like:
-1, --tlsv1         Use TLSv1.0 or greater --tlsv1.0       Use TLSv1.0 or greater --tlsv1.1       Use TLSv1.1 or greater --tlsv1.2       Use TLSv1.2 or greater --tlsv1.3       Use TLSv1.3 or greater If you don't see a line in there about TLS 1.2, you're most likely going to have a problem.  There can be multiple lines, as TLS will negotiate to use the highest version that both sides have.  But if TLS 1.2 does not exist, game over.  

Social Search 5.2 Released!
Added widget for scaled popular search terms Added configurable number of scaled popular search terms to widget and block Block number is in ACP settings, widget number is on the widget settings on the front end when messing around with widgets. Widgets have different scaling CSS calls, just look them up and adjust as needed.

Social Search 5.1 Released!
Quick addition of a scaled text popular searches block to the results page - option in settings. Adjusted margins for searches displayed on Search Wall @Ember Stone

This will NOT adjust the color of the results. Your site's colors are going to be so varied that it isn;t worth my time. You can adjust as you like by just adding the changes you need to your custom.css file.
For now, this will take the 20 most popular results and place them in this block (your mileage may vary based on how well-trafficked your community is + you will need tracked data so new installs maybe give it some time to get that data...). This block is at the moment only available on the search results page - it'll come to the front end widgets soon enough but my plate is full and so on on my end and with 4.5 looming (preview prior to beta is awfully close...) any additions to this will wait for my 4.5 sweep.
Oh yeah, the 20 are randomized on page load to mix it all up. (example above only has 14 - its my newer dev install with very little searching so not all the datas)
Popularity text sizing based on percentages - 10 steps - zero to nine. zero being the 'least most popular', nine being the 'most most popular'.
.ss-scale-0 { font-size: 1em; } .ss-scale-1 { font-size: 1.25em; } .ss-scale-2 { font-size: 1.5em; } .ss-scale-3 { font-size: 1.75em; } .ss-scale-4 { font-size: 2em; } .ss-scale-5 { font-size: 2em; } .ss-scale-6 { font-size: 2.25em; } .ss-scale-7 { font-size: 2.5em; } .ss-scale-8 { font-size: 2.75em; } .ss-scale-9 { font-size: 3em; } That's what I am providing. Copy/paste these into your custom.css and add in any color changes as needed to make the text darker or different colors as the percentages change. If you are not going to tweak the sizing then just remove those font-size bits to save on clutter.
To add this block, go to the Social Search settings and enable it. Note that the recent block and this new most popular block can both be on the page at the same time (as in the screen shot) - configure as you like.
Popularity is based on last 90 days.
Not bad for a request made a couple of hours ago 🍺

On search page on Recent Searches block
That will be nice if you can do here
