I believe that's been fixed in commit
fa70c141552c76cf4dc9666f577bf6b471fa0d50 ("substitute: Reopen connection
upon “Error in the push function” from GnuTLS.").

Closing.

I received the following error when performing a guix pull:

|substitute: guix substitute: error: TLS error in procedure 'handshake':
Error in the pull function.

guix pull: error: You found a bug: the program

failed to compute the derivation for Guix (version:
"cf48f0fc4c40a2ec0b38a445e1e13f37722a0ade"; system: "x86_64-linux";
host version: "ecf92194a55188a9c217d76617378749db063453"; pull-version: 1).
Please report it by email to <bug-guix <at> gnu.org>.

I've seen this kind of error before in other software and I believe it
occurs when a handshake can't be performed in time and the connection is
dropped; I was able to successfully pull a few minutes later under better
conditions. That being said I bring this up because a problem in my network
(I think) is being treated like an error in your program.
