The IceCube Neutrino Observatory is a gigaton-scale Cherenkov detector located within the South Pole glacial ice. The detector's sensitivity to neutrino signals from GeV to PeV energies allows for probes into hypothetical energy-sensitive nonstandard interactions (NSI). Using the range of matter baselines provided by Earth, IceCube has been able to constrain neutral-current NSI by searching for deviations from the standard prediction of neutrino fluxes. With a 90% confidence interval of $-0.0041 \leq \epsilon_{\mu \tau} \leq 0.0031$, we present the world-leading constraints on the mu-tau flavor-changing parameter from a study 8 years of high-energy (500 GeV - 10 TeV) upgoing muon tracks.
