That could definitely be the case. We will switch to use NDK soon, hopefully that handles relay connections better.

Hmm, to me this looks like the connection to the relay was dropping and not re-connecting properly, and from the log requests were published when the relay was not connected, and also it was waiting for a response after a relay disconnection. is this possible? @ek

looks more that your node funding source cannot create the invoice, but the connection is OK.
Did you checked your node logs? Maybe the LN graph is not well synced.
