"Electrs failed to index the sweep after 10 seconds" in regtest.rs

[schoen]

Simplex version

0.0.4

What happened?

I get this error when running simplex regtest after installing with simplexup.

schoen@vergil:~/src/smplx/examples/basic$ lsb_release -a

Running simplex test gives the same error message but less verbosely.

Minimal reproduction steps

simplex regtest reliably gives this error for me.
