Curl_fetch_memory error

hello everyone. I work in the R language on github and have a problem with one of my repos:

https://travis-ci.org/RobinHankin/lorentz

Following a succesful build there is an error which I am stuck on:

Error in curl::curl_fetch_memory(url, handle = handle) :
4808 Timeout was reached: [codecov.io] Connection timed out after 10000 milliseconds
4809Calls: codecov ... request_fetch -> request_fetch.write_memory -> <Anonymous>
4810Execution halted

Can anyone advise?
