Good news re C2 & Jewels.
More basic issue here, how can I get more connections when I stake? currently only 2.
Which version of the wallet are you using? The last release by UdjinM6 a month ago fixed the connections issue but you have to resync the entire block chain, but there is also a bootstrap for that on the block explorer, the link should be at the top of the page.
