The Algolia CLI Old[1] is now deprecated and no longer supported, the Algolia CLI Old may return the "No server found, verify your proxy/network" error.
There is a workaround, where you can explicitly set thebatchSize. Theimportcommand takes an optionalbatchSizeargument using the-bflag. Using this should circumvent the network speed test altogether.
It is highly recommended to switch to the new CLI[2][3] as it is an officially supported library by Algolia, this has been designed to be easier and more convenient to use in build processes.
More information and insight into this error can be found in this GitHub issue: https://github.com/algolia/algolia-cli-old/issues/60
